RESULTS
Consolidated Results
(Unless otherwise noted the financial numbers below exclude the Identified Item)
For the third quarter of 2024, the Company reported net sales of $3.1 billion, net income of $183 million, or $1.41 per share, and EBITDA (earnings before interest expense, income taxes, depreciation and amortization) of $580 million. During the third quarter of 2024, we experienced extended maintenance outages at our ethylene JV facility, which drove higher purchases of ethylene feedstock, and one of our chlorovinyl facilities.
Third quarter 2024 sales of $3.1 billion declined by 3% compared to the second quarter of 2024. Company sales volume decreased 4% sequentially while average sales price increased 1% from the previous quarter. Net income of $183 million decreased by $130 million as compared to the second quarter of 2024. The sequential decrease in net income compared to the prior quarter was primarily due to the aforementioned production outages, higher ethylene feedstock costs and lower sales volume.
EBITDA of $580 million for the third quarter of 2024 decreased by $102 million as compared to third quarter 2023 EBITDA of $682 million. Third quarter 2024 EBITDA decreased by $164 million as compared to second quarter 2024 EBITDA of $744 million.
A reconciliation of EBITDA (including and excluding the Identified Item) to net income, income from operations and net cash provided by operating activities can be found in the financial schedules at the end of this press release. Reconciliations of segment EBITDA (including and excluding the Identified Item) to net income and income from operations can be found in the financial schedules at the end of this press release.
Mothball Expenses ("Identified Item")
During the third quarter of 2024, the Company accrued $75 million of mothball expenses in the Performance and Essential Materials segment related to the previously announced decision to mothball two units within our European epoxy business to align our manufacturing footprint and costs with changing global conditions. Consistent with our previous disclosure, cash outflows related to these mothball expenses are expected to occur over several years starting in 2025.
Cash and Debt
Net cash provided by operating activities was $474 million for the third quarter of 2024 and capital expenditures were $220 million. $300 million of maturing senior notes were redeemed during the quarter, resulting in cash and cash equivalents of $2.9 billion and total debt of $4.6 billion as of September 30, 2024.
Performance and Essential Materials Segment
(Unless otherwise noted the financial numbers below exclude the Identified Item)
For the third quarter of 2024, PEM sales of $2.0 billion were in line with the second quarter of 2024. PEM sales volume decreased 1% quarter-over-quarter while average sales price increased 1% sequentially.
PEM income from operations was $66 million in the third quarter of 2024 as compared to income from operations of $157 million in the second quarter of 2024. This sequential decrease of $91 million was primarily driven by unplanned outages and higher ethylene feedstock costs, which were partially offset by higher average sales price, particularly for polyethylene.
ii

Compared to the prior year period, PEM income from operations decreased by $39 million. This decrease in income from operations versus the third quarter of 2023 was primarily driven by unplanned outages and lower average sales price that were partially offset by higher sales volume, particularly for chlorine, caustic soda and epoxy resin.
Housing and Infrastructure Products Segment
For the third quarter of 2024, HIP sales of $1.1 billion decreased from second quarter of 2024 sales of $1.2 billion as a result of lower sales volume due to slower North American residential construction activity and weather disruptions.
HIP income from operations was $202 million in the third quarter of 2024 as compared to income from operations of $266 million in the second quarter of 2024. This sequential decrease of $64 million was primarily due to lower sales volume at most product categories as a result of slower North American residential construction activity and weather disruptions.
Compared to the prior year period, HIP income from operations decreased by $54 million. This decrease in income from operations versus the third quarter of 2023 was primarily driven by lower average sales price and lower sales volume, particularly for pipe & fittings.
EXECUTIVE COMMENTARY
"During the third quarter of 2024, global macroeconomic trends modestly improved from the environment we saw in the second quarter of 2024 with relatively solid and improving conditions in North America, a continuing recovery in Asia, and slow improvement in Europe. Demand for our products during the third quarter was consistent with these market conditions, and our third quarter financial results would have reflected these trends if it had not been for extended maintenance outages at two plants during the quarter in our PEM segment. While we are disappointed with this operational performance, we have completed the maintenance and these plants have returned to service. Furthermore, we are applying the lessons learned from these incidents to other plants, while increasing our focus on preventive maintenance across our organization to improve the reliability of our plants," said Jean-Marc Gilson, President and Chief Executive Officer.
"The pace of the recovery from the recent trough in global industrial and manufacturing activity remains uneven. However, recent monetary and fiscal stimulus, including actions by the Federal Reserve and the Chinese government, have the potential to accelerate the pace and duration of the macroeconomic recovery. Meanwhile, we will continue to focus on our levers for growth, including developing and commercializing innovative new products to help our customers address their needs, improving the profitability and reliability of our plants, and redeploying our investment-grade balance sheet to create long-term shareholder value," concluded Mr. Gilson.

Forward-Looking Statements
The statements in this release and the related teleconference relating to matters that are not historical facts, including statements regarding our outlook for the performance of our business segments, global macroeconomic conditions, continuing stabilization or increases in sales prices, volumes, margins and profitability in both domestic and export markets for most of our products, industrial, manufacturing, residential construction and infrastructure activity in our target markets, our ability to weather economic volatility, raw material costs, higher energy prices, the earnings potential of our assets, monetary and fiscal policies domestically and abroad, the pace and duration of economic recovery, our ability to improve profitability and reliability of our plants, future preventative maintenance activities, our ability to continue to execute our strategies, and our ability to create long-term value for our shareholders are forward-looking statements.
These forward-looking statements are subject to significant risks and uncertainties. Actual results could differ materially, based on factors including, but not limited to: general economic and business conditions; the cyclical nature of the chemical and building products industries; the availability, cost and volatility of raw materials and energy; the results of acquisitions and our integration efforts; uncertainties associated with the United States, European and worldwide economies, including those due to political tensions and conflict in the Middle East, Russia and Ukraine and elsewhere; uncertainties associated with pandemic infectious diseases; uncertainties associated with climate change; the potential impact on demand for ethylene, polyethylene and polyvinyl chloride due to initiatives such as recycling and customers seeking alternatives to polymers; current and potential governmental regulatory actions in the United States and other countries; industry production capacity and operating rates; the supply/demand balance for Westlake's products; competitive products and pricing pressures; instability in the credit and financial markets; access to capital markets; terrorist acts; operating interruptions (including explosions, fires, weather-related incidents, unscheduled downtime and environmental risks); changes in laws and regulations, including trade policies; technological developments; information systems failures and cyberattacks; foreign currency exchange risks; our ability to implement our business strategies; creditworthiness of our customers; the effect and results of litigation and settlements of litigation; and other risk factors. For more detailed information about the factors that could cause actual results to differ materially, please refer to Westlake's Annual Report on Form 10-K for the year ended December 31, 2023, which was filed with the SEC in February 2024, and Westlake's Quarterly Report on Form 10-Q for the quarter ended June 30, 2024, which was filed with the SEC in August 2024.
Use of Non-GAAP Financial Measures
This release makes reference to certain "non-GAAP" financial measures, such as EBITDA, EBITDA margin and certain financial measures adjusted to exclude the effect of the Identified Item, 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, EBITDA margin and certain financial measures that exclude the effect of the Identified Item, 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 (including and excluding the Identified Item), and (ii) segment EBITDA to segment income from operations (including and excluding the Identified Item) can be found in the financial schedules at the end of this press release.
