Westlake Corporation Reports Third Quarter 2025 Results

Westlake Corporation (NYSE:WLK) (the "Company" or "Westlake") today announced third quarter 2025 results.

BUSINESS HIGHLIGHTS

In the third quarter of 2025, Westlake reported net sales of $2.8 billion, a net loss of $782 million, or $6.06 per share, and EBITDA (earnings before interest expense, income taxes, depreciation and amortization) of ($431) million. Earnings in the third quarter were impacted by a non-cash charge of $727 million to fully impair the goodwill associated with our North American chlorovinyls business ("Chlorovinyls Impairment") as well as $17 million of accrued expenses for previously announced asset shutdowns (the "Identified Items"), which are included in the Performance and Essential Materials segment financial results. Excluding the Identified Items, the net loss in the third quarter of 2025 was $38 million, or $0.29 per share, and EBITDA was $313 million.

Compared to the second quarter of 2025, EBITDA excluding Identified Items of $313 million decreased by $27 million primarily due to lower average sales price in our PEM segment and lower sales volume in our HIP segment.

Westlake's third quarter of 2025 sales volume decreased 1% and average sales price decreased by 2% as compared to the second quarter of 2025. Housing and Infrastructure Products sales decreased 6% sequentially, driven by a 6% decrease in sales volume and unchanged average sales price. Performance and Essential Materials sales decreased 3% over the same period of time as a higher sales volume was more than offset by a 4% decline in average sales price.

EBITDA excluding Identified Items of $313 million was lower than the third quarter of 2024 EBITDA excluding Identified Items of $580 million primarily due to lower average sales price and margin as well as lower sales volume in our PEM segment. Additionally, lower average sales price and several period-related administrative, restructuring and integration expenses in our HIP segment also contributed to the lower year-over-year EBITDA excluding Identified Items.

EXECUTIVE COMMENTARY

"Global macroeconomic conditions remained challenging throughout the third quarter of 2025 with continued weakness in industrial and manufacturing activity putting pressure on sales prices and margins in our PEM segment, particularly for chlorovinyls. As a result, during the third quarter we recorded a non-cash impairment charge of $727 million for all of the goodwill associated with PEM's North American Chlorovinyls business. We remain committed to this business as the global need for its products, which are critical to industries ranging from building materials to water to manufacturing, remains intact. We have taken actions to reduce costs to deliver the earnings it is capable of generating and we will assess opportunities to optimize its footprint to return it to levels of profitability that provide an appropriate return on investment," said Jean-Marc Gilson, President and Chief Executive Officer.

"Our HIP segment performed very well, holding sales in line with the prior-year period against a backdrop of slowing North American residential construction activity. HIP remains well positioned to continue to outgrow the market by 'winning with the winners' through product innovation and our solid position as a preferred supplier to large, national homebuilders and distributors," continued Mr. Gilson.

"Looking ahead to next year, we expect our margins and earnings to be supported by actions that we are taking to improve our profitability. First, better plant reliability should improve EBITDA. Second, we have identified $200 million of cost savings that we expect to achieve in 2026. Third, footprint optimization actions that we have already taken, including the Pernis Shutdown, will remove approximately $100 million of annual losses starting in 2026. We believe that these actions will contribute to margins and earnings next year and for years to come," concluded Mr. Gilson.

RESULTS

Consolidated Results

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

For the three months ended September 30, 2025, the Company reported a quarterly net loss of $38 million, or $0.29 per share, on net sales of $2.8 billion compared to the net loss of $12 million reported in the second quarter of 2025. Sequentially, earnings were impacted by lower average sales price in our PEM segment and lower sales volume in our HIP segment, which were partially offset by higher sales volume in our PEM segment.

The third quarter of 2025 net loss of $38 million was $221 million below the third quarter of 2024 primarily due to lower average sales price and margin, particularly in our PEM segment as a result of unfavorable changes in the global supply-demand balance for many of PEM's products as a result of weaker global industrial and manufacturing demand.

EBITDA of $313 million for the third quarter of 2025 decreased by $27 million compared to second quarter 2025 as a result of lower average sales price and margin in our PEM segment and lower sales volume in our HIP segment, which were partially offset by a lower impact from planned turnarounds and unplanned outages in our PEM segment.

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.

Expenses Regarding the Chlorovinyls Impairment and Facility Closures ("Identified Items")

During the third quarter of 2025, the Company recorded a non-cash impairment charge of $727 million representing all of the goodwill associated with the North American Chlorovinyls reporting unit. Additionally, during the third quarter of 2025, the Company accrued $17 million of expenses related to previously- announced asset shutdowns.

Cash, Investments and Debt

Net cash provided by operating activities was $182 million for the third quarter of 2025 and capital expenditures were $239 million. As of September 30, 2025, cash, cash equivalents and fixed-income investments were $2.1 billion and total debt was $4.7 billion.

Housing and Infrastructure Products Segment

For the third quarter of 2025, Housing and Infrastructure Products income from operations of $151 million decreased by $71 million as compared to the second quarter of 2025. This decrease in income from operations versus the prior quarter was primarily due to lower sales volume in Pipe & Fittings and Building Products due to the timing of customer orders between the second and third quarters.

Compared to the third quarter of 2024, Housing and Infrastructure Products income from operations decreased by $51 million. The year-over-year decrease was the result of lower average sales price and margins, particularly in Pipe & Fittings, and several period-related expenses.

Performance and Essential Materials Segment

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

For the third quarter of 2025, Performance and Essential Materials loss from operations of $158 million decreased by $30 million as compared to the second quarter of 2025. This decrease in loss from operations versus the prior quarter was primarily driven by a lower impact from planned turnarounds and unplanned outages, which contributed to an increase in sales volume, particularly for caustic soda. Average sales price declined 4% from the second quarter of 2025, primarily driven by lower prices for PVC resin and unfavorable sales mix with higher sales in the export markets where pricing is typically lower.

Performance and Essential Materials loss from operations was $158 million in the third quarter of 2025 as compared to income from operations of $66 million in the third quarter of 2024. The year-over-year decrease was primarily due to a 7% decline in average sales price, particularly for PVC resin, and a 6% decline in sales volume, particularly for chlorine.

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 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 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 operations, 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 other measures that exclude the effects of 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 Identified Items can be found in the financial schedules at the end of this press release.
