Waste Connections Q1 2026 Results: Strong Execution Meets Overvaluation Concerns

What happened

Waste Connections reported first-quarter 2026 results with revenue and adjusted EBITDA above expectations, highlighting upside from commodities, organic growth, and acquisitions. The company maintained an adjusted EBITDA margin of 32.5%, aligning with historical performance despite ongoing volume softness and environmental headwinds. However, the DeepValue master report rates the stock as a 'POTENTIAL SELL' due to elevated valuation multiples of ~71x P/E and ~22x EV/EBITDA, which discount much of the operational strength. The report emphasizes risks such as net debt/EBITDA of 3.49x, recurring environmental charges, and a capital-intensive acquisition strategy that could strain free cash flow. While this quarter reinforces the price-led growth narrative, it does not address the core issue of limited valuation cushion if execution falters.

Implication

The Q1 2026 performance confirms Waste Connections' operational resilience and pricing power, supporting its defensive compounder image in the waste sector. Yet, the DeepValue analysis underscores that the stock trades at rich multiples, offering little margin of safety against potential setbacks like acquisition integration issues or environmental liabilities. With a 'POTENTIAL SELL' rating and an attractive entry point at $155, current levels near $171 suggest limited upside, especially given high leverage and recurring capex demands. The acquisition-heavy model increases financial risk, and any slowdown in mid-single-digit organic growth could trigger multiple compression. Therefore, investors are advised to trim positions above $190 or wait for a price reset to the $155 range before considering new exposure.

Thesis delta

The Q1 2026 results do not shift the investment thesis; they validate Waste Connections' ability to deliver on near-term targets but fail to mitigate the overvaluation and financial risks highlighted in the DeepValue report. The maintained EBITDA margin of 32.5% is consistent with past performance, yet the stock's premium multiples and dependence on flawless execution remain unchanged concerns. Thus, the recommendation stands to avoid new positions until either the price declines to the attractive entry level or evidence emerges of sustained free-cash-flow growth beyond current expectations.
