Casella’s (CWST) Growth Machine Is Outrunning Its Own Profits

On August 6, Casella Waste Systems (NASDAQ: CWST ) reported second-quarter revenue of $543.7 million, up 16.9% from a year earlier, alongside guidance that was raised on the top line and cut on the bottom line in the same release. Adjusted EBITDA jumped 12.5% to $123.2 million, but GAAP net income slid 27.6% to $3.8 million. That split between the metrics investors watch closely and the number that actually reaches shareholders is the story of this quarter.

Casella closed five acquisitions in 2026 with roughly $165 million in combined annualized revenue, and that buying spree shows up directly in the top line. Revenue rose $78.4 million to $543.7 million for the quarter, with growth coming from acquisitions closed in prior periods rolling over into this year's results, along with National Accounts growth in the Resource Solutions segment.

Pricing did its part too. Solid waste pricing for the quarter climbed 5.5%, made up of 5.8% collection price growth and 4.7% disposal price growth, while municipal solid waste and construction and demolition pricing at the landfills grew 4.5%. Landfill volumes rose at the same time, helped by both third-party sales and internalization efforts, meaning Casella pushed prices higher without giving up tonnage. Adjusted Net Income reached $25.3 million, up 4.6%, and six-month net cash from operations climbed 15.3% to $161 million, with Adjusted Free Cash Flow up 10.3% to $78.1 million.

Management responded by raising full-year revenue guidance to a range of $2.09 billion to $2.11 billion, up from the prior $2.06 billion to $2.08 billion range, and kept its Adjusted EBITDA, operating cash flow, and Adjusted Free Cash Flow targets unchanged.

The same quarter that produced double-digit revenue growth delivered a shrinking bottom line. Net income fell to $3.8 million from $5.2 million a year earlier, a 27.6% decline, driven by higher depreciation and amortization tied to acquisition growth along with higher interest expense. Operating income grew just 3.6% to $20.0 million even as revenue grew nearly five times faster, a sign of how much of the acquisition-fueled growth is getting absorbed by the costs of running a bigger company.

Fuel prices rose sharply during the quarter and stayed elevated through June, and while floating fuel recovery fees offset the added expense, that mechanism itself created a 40 basis point headwind to Adjusted EBITDA margins. Casella also lowered its full-year net income guidance to a range of $0 to $6 million, down from the previous $4 million to $10 million range, even as it raised revenue guidance in the same release.
