Casella Waste Systems, Inc. closed its acquisition of Star Waste Systems, LLC on April 1, 2026, adding roughly $100 million in annualized revenue to the company’s portfolio and deepening its presence in the Boston market. The transaction brings three solid‑waste collection locations and a construction‑and‑demolition processing and transfer station into Casella’s network, immediately increasing collection density in a region where the company competes with Republic Services, Waste Connections and WM.

The acquisition is a classic tuck‑in that aligns with Casella’s stated strategy of pursuing targeted deals that enhance geographic coverage and operational control. By adding Star Waste’s assets, Casella gains a stronger foothold in eastern Massachusetts and southern New Hampshire, markets that have historically been high‑margin and high‑growth for the company. The deal also supports Casella’s broader pipeline, which the company has described as roughly $500 million in potential opportunities, and represents the first acquisition since the transition of the CEO role to Ned Coletta at the start of 2026.

Financially, the transaction was funded through cash on hand and available capacity under Casella’s revolving credit facility, underscoring the company’s healthy liquidity position. In the fourth quarter of fiscal 2025, Casella reported an Adjusted EBITDA of $107 million—up 12.7% from the prior year—and an Adjusted Free Cash Flow of $179.9 million, up 13.6%. The company also posted an 18% increase in revenue for fiscal 2025, reaching $1.837 billion, a growth rate that the acquisition is expected to accelerate.

Management highlighted the strategic value of the deal. “We are excited to welcome the Star Waste team to Casella. This acquisition strategically augments our asset positioning and enhances our collection density in the highly attractive Boston market. We look forward to working with Star Waste’s employees to further build on their strong reputation for exceptional customer service,” said President and CEO Ned Coletta. “With the acquisition of Star Waste, we have acquired four businesses year‑to‑date, with total annualized revenues of approximately $150 million. This is a strong start to 2026, and positions us well for continued growth and strategic execution.” Coletta also noted, “I’m energized by the opportunities ahead and confident in our ability to continue building long‑term value for our shareholders, customers, and employees. We closed the fourth quarter with performance that reflects sustained organic growth, meaningful operating improvement, and continued strategic momentum across the business.”

The Boston market remains one of the most competitive in the United States, with several large waste‑management players vying for market share. By adding Star Waste’s assets, Casella not only increases its collection density but also gains operational efficiencies that can translate into higher margins and improved service levels. The acquisition therefore strengthens Casella’s competitive position and supports its long‑term growth strategy in a high‑margin region.
