Why Casella Waste Systems stock is in focus after revised 2026 guidance

Casella Waste Systems (CWST) has drawn investor attention after revising its 2026 outlook, lifting expected revenues to a range of US$2.060b to US$2.080b while cutting projected net income to US$4 million to US$10 million.

This update arrived alongside first quarter results to March 31, 2026, with sales of US$457.33 million compared with US$417.10 million a year earlier and a net loss of US$5.54 million compared with US$4.81 million previously.

At a share price of US$85.45, Casella Waste Systems has a 7 day share price return of 7.82%. The 90 day share price return shows an 18.35% decline, and the 1 year total shareholder return shows a 27.87% loss. This points to momentum that has faded as investors weigh higher revenue guidance against lower profit expectations.

With the stock down 27.87% over the past year and trading at a discount to some analyst and intrinsic estimates, you have to ask: Is Casella Waste Systems undervalued, or is the market already pricing in its future growth?

Most Popular Narrative: 24.2% Undervalued

Casella Waste Systems' most followed narrative points to a fair value of $112.80 against the last close of $85.45, framing the current share price as meaningfully below that estimate and focusing attention on how future earnings and margins might bridge that gap.

The heightened focus among municipalities, universities, and commercial clients on sustainability and ESG-driven solutions is increasing demand for Casella's Resource Solutions segment, strengthened by recent investments in upgraded recycling facilities and innovative processing capabilities, supporting top-line revenue growth and resiliency against commodity price swings.

Curious what kind of revenue trajectory, margin profile, and earnings power are baked into that view, and how long it could take to get there? The narrative lays out a detailed path, with specific growth rates and profitability targets that underpin the $112.80 fair value, and it connects those assumptions directly to landfill integration, acquisitions, and cost efficiencies.

Result: Fair Value of $112.80 (UNDERVALUED)

However, you also need to factor in that acquisition integration issues, along with higher labor and capital costs, could pressure margins and weaken the bullish narrative.

Another Angle on Valuation: Price to Sales Sends a Different Signal

While the SWS DCF model suggests Casella Waste Systems is undervalued, the simple P/S check tells a different story. The stock trades on a 2.9x P/S ratio, compared with 1.1x for the US Commercial Services industry and a fair ratio of 1.6x, which points to valuation risk if growth or margins fall short. So which signal do you put more weight on?
