Waste Connections Q2 Results: Solid Execution, But Valuation Stays Too Rich

What happened

Waste Connections reported Q2 2026 earnings, with core solid-waste pricing up 6-7% driving revenue growth, but volumes continued to decline as the company exits low-margin contracts. EBITDA margins expanded modestly to around 34%, reflecting operational efficiencies and mix improvement, but environmental charges of $30 million again weighed on GAAP net income. The company raised its full-year guidance slightly, pointing to $1.3-1.35 billion in adjusted free cash flow, but net debt/EBITDA remains elevated at 3.3x due to heavy M&A spending. Management reiterated its price-over-volume strategy and expects continued margin expansion, though organic volume trends remain negative and competitive pushback on pricing could intensify. At ~$171, the stock trades at 71x trailing earnings and 22x EV/EBITDA, leaving minimal room for disappointment—the Q2 results do little to close the valuation gap with peers.

Implication

Waste Connections’ Q2 earnings confirm steady price-led growth and margin progress, but the stock’s 71x P/E already fully discounts these fundamentals. With net debt/EBITDA at 3.3x and headwinds from environmental liabilities and negative volume, the risk/reward remains unfavorable. We recommend trimming positions above $190 and avoiding new entries until the stock falls to $155, where the FCF yield would approach 4% and provide a better margin of safety. The base case valuation of $180 implies limited upside from current levels, while the bear case of $150 suggests ~12% downside, underscoring the asymmetry.

Thesis delta

Q2 2026 results confirm Waste Connections’ ability to drive price-led growth and margin expansion, but also highlight persistent environmental charges and negative volume trends. The slight guidance raise and consistent pricing power do not change our view that the stock is overvalued at 71x earnings. Our thesis shifts toward a more cautious stance as execution risks from M&A integration and leverage remain underappreciated by the market.
