Westlake Corporation reported a strong Q2 2026 recovery, with net sales of $3,271 million, up 11% year over year, and net income attributable to Westlake of $260 million versus a $142 million loss a year earlier; diluted EPS was $2.01. EBITDA rose to $679 million and gross margin improved to 20% from 9%, driven by higher polyethylene and PVC resin prices, stronger pipe and fittings, caustic soda and epoxy volumes, and lower fuel and ethane feedstock costs, partly offset by lower pipe and fittings pricing.
For the first half of 2026, net income attributable to Westlake was $91 million compared with a $182 million loss in 2025, as EBITDA increased to $829 million. Free Cash Flow remained negative at $192 million due to $416 million of capital expenditures, $171 million of business acquisitions and the $496 million redemption of 3.60% 2026 Senior Notes, leaving cash, cash equivalents and restricted cash at $1,660 million and long-term debt at $5,067 million as of June 30, 2026. The company closed a new $1.5 billion unsecured revolving credit facility maturing in 2031, completed the $124 million ACI acquisition and a $109 million Wilhelmshaven PVC/VCM plant purchase, and recorded a $67 million charge to settle certain U.S. PVC pipe antitrust litigation. Environmental and plant-closure liabilities, including the Pernis facility and North American chlorovinyls and styrene shutdowns, remain meaningful but are being addressed over multi-year plans.
Westlake Corporation reported a significantly weaker first quarter of 2026. Net sales fell to $2.65 billion from $2.85 billion, and net loss attributable to the company widened to $169 million, or $(1.31) per share, versus a $40 million loss, or $(0.31) per share, a year earlier.
Gross profit dropped to $112 million with margin halved to 4% from 8%, driven by lower volumes and prices for PVC resin, polyethylene, caustic soda, chlorine and building products, as well as higher fuel costs and a $67 million litigation-related charge. EBITDA declined to $150 million from $288 million.
The Housing and Infrastructure Products segment remained profitable but saw income from operations fall to $56 million from $148 million, while the Performance and Essential Materials segment’s loss from operations deepened to $211 million. Westlake completed the $124 million ACI acquisition, invested $209 million in capital expenditures, used $94 million in operating cash flow, and ended the quarter with $2.27 billion in cash and cash equivalents plus $205 million in available-for-sale securities. It also put in place a new $1.5 billion revolving credit facility and plans to redeem $496 million of 3.60% 2026 senior notes.
Westlake Corporation reported third‑quarter results marked by a non‑cash goodwill impairment and lower sales. Net sales were $2,838 million versus $3,117 million a year ago. The quarter included a $727 million non‑cash goodwill impairment tied to the North American Chlorovinyls reporting unit, leading to a net loss of $782 million and diluted EPS of $(6.06).
Year to date, net sales were $8,637 million and operating cash flow totaled $240 million (down from $880 million in the prior year), while capital expenditures reached $754 million. Cash and cash equivalents were $1,927 million with $198 million in available‑for‑sale securities, and the revolving credit facility provided $1,500 million of additional availability. Long‑term debt carried at $4,656 million included a current portion of $750 million due 2026 notes.
The Housing and Infrastructure Products segment delivered income from operations of $151 million, while Performance and Essential Materials posted a loss reflecting the impairment. The company declared a quarterly dividend of $0.5300 per share. Shares outstanding were 128,273,220 as of October 24, 2025.
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.
