WCN · PEAD ↑ 80

Waste Connections reported Q3 2026 EPS of $1.58 on 2026-10-21, beating the $1.52 consensus by $0.06 (+3.9%).

Print-day reaction was -0.7% versus the prior close, a muted negative response that belied the earnings beat. The overnight gap to the T+1 open extended the softness by another -1.1%, suggesting initial skepticism in after-hours trading. Over the following two sessions, however, the stock surged +10.0%, decisively reversing the post-print weakness and absorbing the overnight fade with room to spare. Cumulative abnormal return of +10.7% versus SPY.US firmly places this in PEAD long territory — drift has overridden the initial reaction; the read holds through 2027-01-18.
