Meaningful actions taken in 2025 to optimize footprint, improve plant reliability, and structurally reduce costs expected to provide earnings improvement in 2026

HOUSTON, February 24, 2026–(BUSINESS WIRE)–Westlake Corporation (NYSE: WLK) (the “Company” or “Westlake”) today announced fourth quarter and full year 2025 results.

BUSINESS HIGHLIGHTS

In the fourth quarter of 2025, Westlake reported net sales of $2.5 billion, a net loss of $544 million, or $4.22 per share, and EBITDA (earnings before interest expense, income taxes, depreciation and amortization) of ($315) million. Earnings in the fourth quarter were impacted by $393 million of charges related to the shutdown of three North American chlorovinyls plants and one styrene plant and $102 million of accrued expenses related to the Pernis shutdown (together, “PEM shutdown expenses”) as well as $16 million of restructuring and related expenses in our HIP segment (“HIP restructuring expenses”) for a combined $511 million impact (“the Identified Items”). Excluding the effects of the Identified Items, the net loss in the fourth quarter of 2025 was $33 million, or $0.25 per share, and EBITDA was $196 million.

Story Continues  

Excluding the Identified Items, for the full year of 2025 Westlake reported net sales of $11.2 billion, a net loss of $116 million, or $0.90 per share and EBITDA of $1.1 billion. Compared to the prior-year financial results, the Company’s 2025 results were impacted by lower average sales price, particularly in PEM, lower sales volume, and higher feedstock and energy costs.

Westlake’s fourth quarter of 2025 sales decreased 11% year-over-year, driven by a 7% decline in sales volume and a 4% decline in average sales price. Housing and Infrastructure Products sales decreased 8%, driven by an 8% decline in sales volume and unchanged average sales price. Performance and Essential Materials sales decreased 12% over the same period of time, driven by a 7% decline in sales volume and a 5% decline in average sales price.

EXECUTIVE COMMENTARY

“As 2025 came to a close, our PEM profitability improvement plan began to generate tangible benefits with accelerating realization of our cost savings initiatives and significant strategic action to optimize our North American footprint. As a result, PEM’s EBITDA for the fourth quarter of 2025 exceeded our expectations while HIP’s fourth quarter EBITDA was in-line with our expectations, which reflected the effects of slower housing starts and seasonal weather impacts,” said Jean-Marc Gilson, President and Chief Executive Officer.

“For 2026 our priority is to achieve the PEM profitability improvement plan’s targeted $600 million in EBITDA improvement while growing HIP’s sales and earnings, which are expected to benefit from the January 2026 acquisition of ACI. We are not expecting macroeconomic conditions to be a tailwind to our 2026 goals as global industrial and manufacturing activity remains challenging. However, we are very confident in the ability of our PEM profitability improvement plan to improve earnings in 2026 and we remain well positioned to capitalize on an eventual recovery in global demand,” concluded Mr. Gilson.

RESULTS

Consolidated Results

(Unless otherwise noted the financial numbers below exclude the effects of the Identified Items)

For the three months ended December 31, 2025, the Company reported a quarterly net loss of $33 million, or $0.25 per share, on sales of $2.5 billion compared to the net loss of $38 million reported in the third quarter of 2025. Sequentially, earnings were impacted by lower average sales price, particularly in the PEM segment, and lower sales volume, particularly in the HIP segment.

The fourth quarter of 2025 net loss of $33 million was $40 million below the fourth quarter of 2024 primarily due to the 11% decline in Westlake’s net sales and higher feedstock and energy costs in the PEM segment.

EBITDA of $196 million for the fourth quarter of 2025 decreased by $220 million compared to fourth quarter 2024 EBITDA of $416 million. Fourth quarter 2025 EBITDA decreased by $117 million compared to third quarter 2025 EBITDA of $313 million.

The full year of 2025 net loss of $116 million was $793 million below the full year of 2024 net income of $677 million. Loss from operations of $186 million for the full year of 2025 decreased by $1.1 billion as compared to income from operations of $1.0 billion for the full year of 2024. The decreases in net income and income from operations were primarily due to lower average sales price, particularly in the PEM segment, lower sales volume, higher feedstock and energy costs, and a more significant impact from planned turnarounds and unplanned outages in 2025.

A reconciliation of EBITDA and net income to EBITDA excluding Identified Items and net income excluding Identified Items as well as a reconciliation of EBITDA to net income, income from operations (including and excluding Identified Items) and net cash provided by operating activities as well as a reconciliation of free cash flow to net cash flow provided by operating activities can be found in the financial schedules at the end of this press release.

PEM shutdown expenses and HIP restructuring expenses (“Identified Items”)

As previously announced, during the fourth quarter of 2025 the Company simplified and optimized operations by shutting down three chlorovinyl production facilities and one styrene facility in North America. As a result of these shutdowns, during the fourth quarter of 2025 PEM accrued $386 million of expenses primarily consisting of noncash accelerated depreciation, amortization, and asset write-off charges, and realized a $7 million expense to write-off inventory (recorded in cost of sales). During the fourth quarter of 2025, PEM also accrued $102 million of expenses related to the previously-announced shutdown of the Company’s epoxy site at Pernis, The Netherlands. Additionally, during the fourth quarter of 2025 HIP accrued $13 million of expenses for footprint optimization actions and recognized a $3 million loss on the sale of a compounding business (recorded in other income, net).

Cash, Investments and Debt

Net cash provided by operating activities was $225 million for the fourth quarter of 2025 and capital expenditures were $241 million. As of December 31, 2025, cash, cash equivalents and fixed-income investments were $2.9 billion and total debt was $5.6 billion.

Housing and Infrastructure Products Segment

(Unless otherwise noted the financial numbers below exclude the effects of the Identified Items)

For the fourth quarter of 2025, Housing and Infrastructure Products income from operations of $82 million decreased by $47 million as compared to the fourth quarter of 2024. The year-over-year decrease was the result of lower sales volume, particularly for global compounds, and lower margins.

Sequentially, Housing and Infrastructure Products income from operations decreased by $69 million as compared to the third quarter of 2025. This decrease in income from operations versus the prior quarter was primarily driven by lower sales volume as a result of the typical seasonality of customer demand.

For the full year of 2025, Housing and Infrastructure Products net sales of $4.1 billion decreased by $0.2 billion as compared to 2024. Housing Products net sales of $3.5 billion decreased by $0.1 billion due to lower sales volume, particularly for roofing. Infrastructure Products net sales of $635 million decreased from $673 million in 2024 primarily due to lower average sales price at pipe and fitting and lower sales volume at global compounds. Housing and Infrastructure Products income from operations of $603 million decreased by $204 million as compared to the full year of 2024 primarily due to lower sales volume, particularly in global compounds, and lower average sales price and margins, particularly in pipe and fittings.

Performance and Essential Materials Segment

(Unless otherwise noted the financial numbers below exclude the effects of the Identified Items)

For the fourth quarter of 2025, Performance and Essential Materials loss from operations was $222 million as compared to the fourth quarter of 2024’s loss from operations of $41 million due to lower selling prices for most of our major products, particularly for chlorine and polyethylene, and lower sales volume, particularly for PVC resin, polyethylene and epoxy resin.

Sequentially, Performance and Essential Materials loss from operations for the fourth quarter of 2025 increased by $64 million as compared to the third quarter of 2025. This increase in loss from operations versus the prior quarter was primarily driven by lower average sales price, particularly for polyethylene, chlorine, and PVC resin.

For the full year of 2025, Performance and Essential Materials net sales of $7.0 billion decreased by $0.8 billion as compared to 2024. Performance Materials net sales of $4.0 billion in 2025 decreased by $0.6 billion primarily due to lower sales volume and average sales price for polyethylene and PVC resin and lower epoxy resin sales volume. Essential Materials net sales of $3.0 billion decreased by $0.2 billion from 2024 primarily due to lower chlorine sales volume and average sales price and lower caustic soda sales volume. Performance and Essential Materials loss from operations of $724 million decreased from 2024 due to lower average sales price and margins, lower sales volume, higher feedstock and energy costs, and a more significant impact from planned turnarounds and unplanned outages in 2025.

Use of Non-GAAP Financial Measures

This release makes reference to certain “non-GAAP” financial measures, such as EBITDA, free cash flow and other measures that exclude the effects of the Identified Items, as defined in Regulation G of the U.S. Securities Exchange Act of 1934, as amended. For this purpose, a non-GAAP financial measure is generally defined by the Securities and Exchange Commission (“SEC”) as a numerical measure of a registrant’s historical or future financial performance, financial position or cash flows that (1) excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the most directly comparable measure calculated and presented in accordance with GAAP in the statement of income, balance sheet or statement of cash flows (or equivalent statements) of the registrant; or (2) includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the most directly comparable measure so calculated and presented. We report our financial results in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”), but believe that certain non-GAAP financial measures, such as EBITDA, free cash flow and measures that exclude the effects of the Identified Items, provide useful supplemental information to investors regarding the underlying business trends and performance of the Company’s ongoing operations and are useful for period-over-period comparisons of such operations. These non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, the financial measures prepared in accordance with U.S. GAAP. A reconciliation of (i) EBITDA to net income, income from operations and net cash provided by operating activities, (ii) free cash flow to net cash provided by operating activities, and (iii) other measures reflecting adjustments for the effects of the Identified Items can be found in the financial schedules at the end of this press release.
