Current thesis
The bull case is that the Q1 print may mark an earnings trough: sequential volume improved, PEM pricing strengthened late in the quarter, management expects margin help through at least summer 2026, and the profitability plan plus ACI integration could lift EBITDA from depressed levels.

Confirming evidence
- • Sentiment remains the lead driver in the composite, 7D delta +5.2.
Contradictions & invalidation
- • Litigation and shutdown-related identified items remain a drag, including the $67 million PVC pipe and fittings settlement and $18 million of shutdown-related charges in Q1.
- • North American residential construction remains weak, pressuring HIP volumes and pricing.
- • The bear case is that the quarter reinforced weak core earnings power: Westlake still posted a sizeable loss, PEM EBITDA remained far below last year, HIP guidance shifted to the low end, and the best near-term margin support comes from geopolitically driven price spikes that may not persist.
