Why is Waste Connections stock slipping today?

Waste Connections Inc. shares are experiencing a slight 0.8% decline on today's trading session, currently trading at C$236.26. The market's cautious approach stems from the anticipation of the company's third-quarter 2026 earnings report, which is expected to be released after the market closes. Analysts are projecting earnings of $1.52 per share and revenue of $2.61 billion, both reflecting a 6% increase year-over-year.

Consequently, the market is awaiting a substantial beat in performance to justify the stock's premium valuation. Waste Connections has been under scrutiny due to its exceptionally high price-to-earnings ratio, indicating that even a minor dip in margins or forward guidance could prompt a sharper reaction. Additionally, recent analyst actions, such as Morgan Stanley lowering its price target from $205 to $195 and Citigroup reducing its target from $182 to $175, have further contributed to the cautious sentiment surrounding the stock.

The broader market environment did not provide much support for Waste Connections' decline, with the TSX Composite showing mixed performance due to fluctuating energy prices and mining sector challenges. The loss in shares is primarily attributed to the company-specific factors, such as the imminent earnings release and recent analyst downgrades.

The stock's future direction will depend on the outcomes of the Q3 results and management's presentation of the full-year outlook during their conference call on October 22.
