Deals & partnerships

Star Waste Adds density within existing footprint, strong overlap in Massachusetts, opportunities for integration and operational improvements.

Closed on April 1, 2026. Described as a well-run company with strong management and systems, backed by PE firm Clairvest. Includes a state-of-the-art construction and demo processing facility. Also brings potential future acquisitions in its pipeline.

Multiple unnamed companies Tuck-in opportunities that fit well within existing markets.

Three other acquisitions completed in 2026 in addition to Star Waste. The acquisition pipeline remains very strong.

Risks & headwinds

Acquisition Margin Dilution Q1 FY26

15 basis points

Mitigation:Integration efforts, synergy capture, and application of operating model to improve margins over time, creating a regenerative benefit.

Solid Waste Volume Decline Q1 FY26

-2.5% YoY

Mitigation:Anticipate seasonal upswing in volumes in spring; seeing positive trends through April. Focus on sales pipeline and internalization efforts.

Recycled Commodity Price Impact Q1 FY26

$1 million net impact on revenue

Mitigation:Contract structures share risk with customers by adjusting tip fees in down markets. Expect negative year-over-year comparisons to moderate as the year progresses.

Fuel Cost Increases Q1 FY26

$1.9 million increase in base business costs

Mitigation:Fuel recovery program (floating fees) successfully covered all increases with minimal lag.

Short-term Margin Headwinds (Q2) Q2 FY26

Not quantified, but described as 'some headwinds'

Mitigation:Mid-Atlantic synergies and G&A savings are back-end loaded (Q3/Q4). Focus on Q3 and Q4 for margin improvement.

Q&A highlights

Given $30 million in cost reductions over 3 years from G&A and Mid-Atlantic synergies, should investors expect outsized margin expansion over the next couple of years?

Management confirmed that an above-brand margin improvement opportunity is expected over the next 2-3 years, exceeding the typical 50 basis points of recurring margin expansion in the base business, due to pent-up synergy opportunities and G&A efficiencies.

“Given the, I'll call it, pent-up synergy opportunity in the Mid-Atlantic, it's been delayed by certain factors and the opportunities we see to start to get to the G&A line as a percentage of revenue in a way that the company hasn't really been able to before. We do see an above brand margin improvement opportunity over the next 2 to 3 years, I think that's a fair assumption.”

Detailed narrative

Mid-Atlantic Integration and Synergy Realization

Casella has made significant progress on Mid-Atlantic integration, migrating nearly all customers to its new lead-to-cash system and payment portal, with completion expected next week. This transition allows the company to focus on operational synergies, targeting $5 million in operating cost cuts in 2026 and an additional $10 million over the next two years through route consolidations, automation, and facility consolidations. The company expects these efforts to drive margin expansion in the region, aiming for mid-20% margins and eventually 30% collection margins comparable to its Northeast operations.

G&A Cost Reduction Initiatives

The company is on track to achieve $15 million in targeted G&A savings over the next three years. The first phase, involving credit card convenience fees, will yield savings in the second half of 2026. The second phase in 2027 will eliminate redundant system costs, followed by the final phase in 2027-2028 through back-office automation and AI-enabled tools. These initiatives are expected to improve G&A as a percentage of revenue starting in 2027, generating additional leverage and efficiency gains.

Landfill Permitting and Capacity Expansion

Casella is advancing permitting efforts for significant landfill expansions. The Hakes C&D landfill permit, expected by Q3 2026, will add over 10 years of capacity. The Hyland landfill permit, expected by Q1 2027, aims to more than double its annual permit from 460,000 to 1 million tons per year and add 60 years of capacity. These expansions are critical for addressing the Northeast's disposal capacity imbalance, where about 30% of waste needs to be exported due to lack of local options.

Strategic Acquisitions and Pipeline Strength

The company completed four acquisitions in 2026, totaling approximately $150 million in annualized revenues. The largest, Star Waste (closed April 1), adds $100 million in annualized revenues and provides strategic density in the Greater Boston area. Management views Star Waste as a well-run platform with strong integration opportunities and potential for future tuck-in acquisitions. The acquisition pipeline remains robust, focusing on opportunities that build density within existing footprints.

Landfill Gas Program Development

Casella has four landfill gas-to-energy projects online, including new projects at Chemung and Hyland landfills with Waga, which appear to be operating well in their early stages. These projects are expected to generate several million dollars of EBITDA in 2026. The company's strategy involves partnering with developers who invest the capital, allowing Casella to benefit from royalty streams without direct investment, despite some initial delays in project development.

Northeast Disposal Market Dynamics

Management reiterated its long-term positive outlook for Northeast landfill pricing, expecting mid-single-digit growth due to a persistent supply-demand imbalance. While rail-based disposal options can exert temporary pressure, the high capital intensity and logistical complexity of such solutions, coupled with major companies prioritizing internal tons, limit their merchant market impact. Upcoming closures of ash landfills in Massachusetts and the Brookhaven landfill on Long Island will further tighten regional disposal capacity, creating value for Casella's in-market assets.
