Westlake Corporation’s Q2-25 results deteriorated sharply. Net sales fell 8% YoY to $2.95 bn, while gross profit shrank 61% to $258 mm as PVC, polyethylene and epoxy pricing remained weak and energy costs stayed elevated. A $115 mm restructuring charge tied to the full closure of the Pernis (Netherlands) epoxy site and other integration costs pushed operating results to a $109 mm loss versus a $406 mm profit last year. After interest and taxes, the company posted a net loss attributable to shareholders of $142 mm (-$1.11 EPS), compared with $313 mm (+$2.42 EPS) in Q2-24.
Segment mix worsened. Performance & Essential Materials swung to a $318 mm operating loss (vs. +$157 mm), weighed by lower vinyls/olefins margins and Pernis charges. Housing & Infrastructure Products remained profitable but EBIT slipped 16% to $222 mm on softer demand.
Liquidity remains solid. Cash & equivalents were $2.1 bn, supplemented by a fully undrawn $1.5 bn revolver; long-term debt rose slightly to $4.65 bn, leaving net cash of about -$2.55 bn. Operating cash flow fell to $58 mm (-86% YoY) on lower earnings and working-capital outflows; capex was $515 mm, still skewed to growth and maintenance projects.
Balance-sheet strength allows dividends to continue ($0.525/sh in Q2). Management expects further Pernis closure costs (~$78 mm future plant shutdown & severance) and is assessing impacts of July 2025 U.S. tax changes, which should reduce cash taxes but have minimal EPS effect.
