BUSINESS HIGHLIGHTS
In the second quarter of 2026, Westlake reported net sales of $3.3 billion, net income of $260 million, or $2.01 per share, and EBITDA (earnings before interest expense, income taxes, depreciation and amortization) of $679 million. The Company's second quarter of 2026 financial results benefitted from a higher average sales price in our PEM segment, higher sales volume in our HIP segment, and our three-pillar profitability improvement plan.

Sales volume for Housing and Infrastructure Products in the second quarter increased 6% from the second quarter of 2025 (excluding the effect of the ACI acquisition) while Performance and Essential Materials sales volume increased 7% year-over-year (excluding the effect of plant shutdowns). Overall sales volume for the Company increased 7% from the second quarter of 2025.

ii


Housing and Infrastructure Products second quarter average sales price decreased 3% from the second quarter of 2025 while Performance and Essential Materials average sales price increased 14% year-over-year. Overall average sales price for the Company increased 8% from the second quarter of 2025.

In the second quarter of 2026, HIP's EBITDA margin decreased to 22% from 24% in the second quarter of 2025, while PEM's EBITDA margin, excluding Identified Items, increased to 21% from 3% over the same period of time.
EXECUTIVE COMMENTARY
"The significant improvement in PEM's second quarter earnings underscores its substantial leverage to improving global supply-demand fundamentals, driven in part by logistical disruptions in the Strait of Hormuz, as well as the meaningful actions that we took last year to improve PEM earnings through footprint optimization, cost reduction, and reliability improvement. Meanwhile, despite slower North American residential construction activity and accelerating raw material cost inflation, financial results in our HIP segment were solid in the second quarter with EBITDA growth that was driven by a double-digit increase in pipe & fittings sales volume. During the second quarter, we completed the acquisition of a PVC and VCM production site in Wilhelmshaven, Germany, which adds advantaged logistical assets into our European chlorovinyls business," said Jean‑Marc Gilson, President and Chief Executive Officer.

"The ongoing conflict in the Middle East continues to exacerbate volatility in selling prices and export demand across many of PEM's products, including polyethylene and PVC resin. Regardless of this impact, PEM's earnings should continue to benefit from our three-pillar profitability improvement plan and our globally advantaged North American feedstock and energy cost position. In HIP, slower homebuilding activity due to affordability pressures is being offset by strong demand for pipe and fittings, driven by North American infrastructure investments," Mr. Gilson concluded.

"During the second quarter of 2026 we returned to free cash flow generation, reduced debt by $500 million and replaced our existing revolving credit facility, which had a scheduled expiration in 2027, with a new $1.5 billion revolver that expires in 2031. We continue to prioritize a disciplined approach to capital deployment supported by our strong financial position," added Jonathan Baksht, Senior Vice President and Chief Financial Officer.
RESULTS
Consolidated Results
(Unless otherwise noted the financial numbers below exclude the effects of the Identified Items)
For the three months ended June 30, 2026, the Company reported quarterly net income of $260 million, or $2.01 per share, on net sales of $3.3 billion compared to the net loss of $12 million reported in the second quarter of 2025. Compared to the prior year period, earnings benefited from a higher average sales price and margin in PEM, our three-pillar profitability improvement plan, the ACI acquisition and higher sales volume.

EBITDA of $679 million for the second quarter of 2026 increased by 100% from the second quarter of 2025 EBITDA of $340 million. Second quarter 2026 EBITDA increased by $444 million compared to first quarter of 2026 EBITDA of $235 million.

Reconciliations of non-GAAP financial measures used in this press release (including EBITDA and measures that exclude the effects of the Identified Items) to the most directly comparable GAAP measure can be found in the financial schedules at the end of this press release.
Expenses Regarding Litigation, Facility Closure and Temporary Cessation of Operations ("Identified Items")
During the first quarter of 2026, the Company accrued a $67 million charge to settle certain litigation involving direct purchasers of PVC pipe and fittings in the United States and $18 million of charges related to previously announced facility shutdowns, including the Pernis epoxy facility, certain North American chlorovinyls facilities and a styrene facility. During the second quarter of 2025, the Company accrued $108 million of expenses and wrote-off $15 million of inventory related to the previously announced decision to shut down Pernis and accrued $7 million of expenses to temporarily cease operations of a PVC resin production unit at Huasu.
iii


Cash, Investments and Debt
Net cash provided by operating activities was $318 million for the second quarter of 2026 and capital expenditures were $207 million. During the second quarter of 2026, the Company redeemed the remaining approximately $500 million of its outstanding 3.60% 2026 Senior Notes. As of June 30, 2026, cash, cash equivalents and fixed-income investments were $1.9 billion and total debt was $5.1 billion.
Housing and Infrastructure Products Segment
(Unless otherwise noted the financial numbers below exclude the effects of the Identified Items)
For the second quarter of 2026, Housing and Infrastructure Products income from operations of $212 million decreased by $10 million as compared to the second quarter of 2025. The year-over-year decrease was the result of a lower average sales price and margins, particularly for pipe & fittings. Housing Products net sales of $1.0 billion in the second quarter of 2026 increased by $31 million from the second quarter of 2025 primarily due to higher sales volume, particularly for pipe & fittings and siding & trim. Infrastructure Products net sales of $241 million increased by $61 million from the second quarter of 2025 primarily due to the January 2026 acquisition of ACI.

Sequentially, Housing and Infrastructure Products income from operations increased by $88 million as compared to the first quarter of 2026. This increase in income from operations versus the prior quarter was primarily due to seasonally higher sales volume and higher end market demand for pipe & fittings.
Performance and Essential Materials Segment
(Unless otherwise noted the financial numbers below exclude the effects of the Identified Items)
For the second quarter of 2026, Performance and Essential Materials income from operations was $185 million as compared to the second quarter of 2025's loss from operations of $188 million. The increase in income from operations was due to a 14% increase in average sales price and margin benefits from our three-pillar profitability improvement plan. Performance Materials net sales of $1.2 billion in the second quarter of 2026 increased by $214 million from the second quarter of 2025 primarily due to a higher average sales price for polyethylene and PVC resin. Essential Materials net sales of $783 million increased by $12 million from the second quarter of 2025 primarily due to higher caustic soda sales volume and a higher average sales price.

Sequentially, Performance and Essential Materials income from operations of $185 million for the second quarter of 2026 increased by $379 million as compared to the first quarter of 2026's loss from operations of $194 million. This improvement in income from operations versus the prior quarter was primarily due to a higher average sales price, particularly for polyethylene and PVC resin, and lower North American natural gas costs.

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 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 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) net loss, loss from operations and net cash provided by (used for) operating activities to EBITDA, and (ii) net cash provided by (used for) operating activities to free cash flow 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.

1 Earnings Presentation 2Q 2026


 
2 Second Quarter 2026 Highlights • Higher global oil prices, as a result of the conflict in the Middle East, contributed to PEM’s 21% higher QoQ average sales price, particularly for polyethylene and PVC resin • PEM EBITDA margin expanded QoQ to 21% primarily due to a higher average sales price, 2% higher sales volume(3) and lower natural gas and ethane costs • HIP’s 6% YoY sales volume growth(3), driven by strong Pipe & Fittings demand, supported stable HIP EBITDA despite inflation in transportation and raw material costs • Three-pillar profitability improvement plan delivered ~$150 million of YoY EBITDA benefit in 2Q’26 towards our $600 million full year target • Acquisition of VCM/PVC site in Wilhelmshaven, Germany, with deep-water port access improves the regional competitiveness of our European chlorovinyls business • Retired $500 million of Senior Notes supporting investment-grade rated balance sheet (1) Reconciliation of EBITDA to the applicable GAAP measure can be found on page 11 (2) Includes investments in available-for-sale securities (3) Excludes the impact of plant closures and the ACI acquisition. Certain of PEM's North America chlorovinyls production facilities ceased operations in December 2025, including (i) the polyvinyl chloride plant at the Aberdeen, Mississippi facility, (ii) the vinyl chloride monomer plant at the Lake Charles, Louisiana North facility and (iii) a diaphragm chlor-alkali unit at the Lake Charles, Louisiana South facility, as well as the styrene production plant located at the Lake Charles, Louisiana facility. The PVC resin production unit owned by the Huasu joint venture ceased operations in June 2025. In January 2026, HIP completed the acquisition of ACI. 2Q 2026 Financial Results $679M EBITDA(1) $3.3B Net Sales $1.9B Cash, Equivalents and Investments(2) Significant net income and EBITDA improvement

See note 3 on page 2. Strong double-digit Pipe & Fittings sales volume growth from infrastructure spending 2Q'26 1Q'26 QoQ% 2Q'25 YoY% Housing Products Sales $1,011 $788 28% $980 3% Infrastructure Products Sales $241 $205 18% $180 34% Total HIP Sales $1,252 $993 26% $1,160 8% Operating Income(1) $212 $124 71% $222 (5%) EBITDA(1,2) $276 $186 48% $275 0% EBITDA Margin (1,3) 22% 19% - 24% - ($ in millions) Maintaining our guidance for HIP’s revenue and EBITDA margin to be at the lower ends of the previously- communicated ranges of $4.4 – $4.6 billion of sales with a 19% – 21% EBITDA margin (1,3) Housing Products 3% YoY sales growth is outpacing the industry-wide trend in North American residential construction spending


 
5 Housing and Infrastructure Products Update 2 Longer-term housing fundamentals remain strong due to decade-plus of under-building, increasingly favorable demographics and popularity of remote work 3 Our 2026 outlook for exterior building products sales volume reflects additional pressure on home affordability from higher building and borrowing costs, but our housing products business continues to outperform a soft market for new home construction 4 Pipe & fittings sales volume growth is supported by higher levels of U.S. infrastructure spending, including data centers 1 The diversity of HIP’s businesses (including housing products, pipe & fittings and compounds) is delivering sales and earnings growth at a time of lower North American residential construction activity

Performance and Essential Materials (“PEM”) Segment Performance(1) Lower QoQ and YoY natural gas and ethane costs benefited EBITDA margin 2Q'26 1Q'26 QoQ% 2Q'25 YoY% Performance Materials Sales $1,236 $1,003 23% $1,022 21% Essential Materials Sales $783 $656 19% $771 2% Total PEM Sales $2,019 $1,659 22% $1,793 13% Operating Income (Loss)(1) $185 ($194) N.M. ($188) N.M. EBITDA(1,2) $416 $36 1,056% $52 700% EBITDA Margin (1,3) 21% 2% - 3% - ($ in millions)


 
7 Performance and Essential Materials Update 2 Selling prices, particularly for polyethylene and PVC resin, have exhibited a high degree of volatility in 2026 due to the significant moves in oil prices as a result of the conflict in the Middle East 3 Westlake’s high degree of product integration and large offtake of PVC resin to the HIP segment provide less exposure to weaker economies outside North America 4 The significant majority of the company-wide EBITDA uplift in 2026 from our three-pillar profitability improvement plan is expected to benefit PEM; improved reliability and production drove higher sales volume in 2Q’26 with an expectation for this to continue in 2H’26 1 Energy and feedstock advantages in North America (~85% of our global production capacity) and our high degree of vertical integration relative to the global industry positions us to benefit from the steepening global cost curve and serve our customers well
