Casella Waste Systems, Inc. (NASDAQ: CWST) reported a 9.7% increase in fourth-quarter revenue to $469.1 million, driven by strategic acquisitions and disciplined solid waste pricing. Despite the top-line growth, the company recorded a net loss of $2.5 million for the quarter ended December 31, 2025, a sharp reversal from the $4.9 million in net income reported during the same period in 2024. Following the release, shares of the regional waste management provider fell approximately 1.04% to close at $101.28 on February 19, 2026, as investors weighed a slight revenue miss against a significant beat in adjusted earnings.
Acquisitions and Pricing Power Drive Top-Line Expansion
The increase in revenue was primarily attributed to the rollover impact of prior acquisitions and a 4.9% rise in solid waste pricing for the fiscal year. For the full fiscal year 2025, total revenues reached $1.837 billion, an 18.0% increase over the $1.557 billion recorded in 2024.
Management noted that the company successfully completed nine acquisitions in 2025, which added an estimated $115 million in annualized revenues. This expansion strategy continued into the new year with the January 1 closing of Mountain State Waste, contributing an additional $30 million to the company’s annualized revenue base.
Earnings Performance and Margin Analysis
While GAAP net income for the full year declined 41.9% to $7.9 million, non-GAAP metrics provided a more favorable view of the company’s underlying performance.
Adjusted EBITDA: Rose 12.7% to $107.0 million in the fourth quarter and 17.3% to $422.8 million for the full year.
Adjusted Net Income: Reached $80.6 million for the fiscal year 2025, a 2.3% increase compared to 2024.
Operating Income: Fell 35.9% in Q4 to $11.9 million, largely due to higher depreciation and amortization costs associated with recent acquisitions.
The disconnect between GAAP and adjusted figures stems from approximately $234.9 million in depreciation and amortization charges and other non-cash adjustments related to the company’s aggressive M&A playbook.
Strategic Outlook and 2026 Guidance
President and CEO, Edmond “Ned” R. Coletta, expressed confidence in the company’s trajectory, stating that the results for the quarter were in line with expectations and provided momentum for the coming year. The company provided 2026 revenue guidance in the range of $1.970 billion to $1.990 billion, signaling anticipated growth of roughly 7% to 8%.
Fiscal Year 2026 Targets:
Net Income: $16 million to $22 million.
Adjusted EBITDA: $455 million to $465 million.
Adjusted Free Cash Flow: $195 million to $205 million.
The guidance does not include the impact of future acquisitions, focusing instead on organic growth and the integration of existing assets.
Sector and Macroeconomic Context
The North American waste management market remains a resilient yet capital-intensive sector, valued at approximately $1.52 trillion in 2025. Industry leaders like Casella and its larger peers, such as Republic Services (RSG) and Waste Management (WM), are increasingly focusing on technology-driven operations to combat rising labor and transportation costs.
Analysts noted that while Casella’s revenue growth remains robust, its high valuation—trading at a P/E ratio significantly above the sector average—places pressure on the company to deliver consistent margin expansion. The broader industry trend toward “circular economy” principles and landfill reduction continues to drive investment in recycling and waste-to-energy infrastructure.
