Business Commentary:

Strong Financial Performance:

• Westlake Corporation reported net sales of $3.3 billion and EBITDA of $679 million for Q2 2026, showing substantial improvement from both Q1 2026 and Q2 2025.
• The improvement was driven by advantages in feedstock and energy costs, a profitability improvement plan, and growth in the Housing and Infrastructure Products segment.

PEM Segment Earnings Improvement:

• The Performance and Essential Materials (PEM) segment's EBITDA increased by $364 million year-over-year, with a 14% increase in average sales price.
• This was supported by a globally advantaged feedstock and energy position in North America, benefits from the company's three-pillar profitability improvement plan, and lower natural gas and ethane costs.

HIP Segment Growth Amidst Soft Housing Market:

• The Housing and Infrastructure Products (HIP) segment achieved its second-highest quarterly revenue of $1.3 billion, with an 8% year-over-year increase in net sales.
• Despite a soft North American residential construction market, HIP's growth was driven by strong performance in pipe and fittings due to infrastructure investments and a robust housing products business.

Profitability Improvement Plan Impact:

• The company's three-pillar profitability improvement plan contributed approximately $150 million to the year-over-year EBITDA improvement in Q2.
• This plan includes footprint optimization, cost savings, and improved plant reliability, with cost savings actions tracking ahead of schedule.

Strategic Acquisitions and Market Positioning:

• Westlake completed the acquisition of a PVC plant in Wilhelmshaven, Germany, enhancing its European supply chain and manufacturing operations.
• The acquisition aligns with the company's strategy to integrate its European operations with low-cost feedstock from North America, aiming for long-term shareholder value.

Sentiment Analysis:

Overall Tone: Positive

• Management highlighted 'substantial improvement' in EBITDA YOY and sequentially, driven by PEM margin expansion and cost savings. Statements: 'We were very pleased with our overall second quarter results' and 'the foundational strength of Westlake' with 'positive momentum'.

Q&A:

• Question from Hassan Hamed (Alambek Global Advisors): Trying to understand how much of the $150M three-pillar benefit was in PEM vs. HIP, and sustainability of higher PEM profitability.
  Response: The vast majority of the $150M benefit is in PEM; savings are sustainable, with $300M achieved YTD and full $600M target expected for 2026.

• Question from Kevin McCarthy (Vertical Research Partners): Update on low density polyethylene price trajectory and market color.
  Response: Polyethylene prices up 25% YTD; July not settled, but August contracts up 5%. Expect price to be higher than prior year by year-end.

• Question from David Bellinger (Docha Bank): Polyethylene export % in Q2/H1 and caustic expectations for back half.
  Response: PEM exports 10-20% of production, less than competitors. Caustic demand solid, prices up 75% YTD; expect H2 avg higher than H1.

• Question from Patrick Cunningham (Citi): Characterize PVC export demand and outlook for H2.
  Response: Export markets subdued after March Chinese flood but picking up; expect year-end PVC price higher than prior year.

• Question from Pete Osterland (Truist Securities): Remaining work to meet $600M cost target and cadence of earnings improvement.
  Response: $600M target maintained; already at run rate with consistent benefits expected. Q3 impact similar to Q2.

• Question from Duffy Fisher (Goldman Sachs): Drivers of expected margin decline in HIP H2.
  Response: Margin decline due to mix, pull-forward from Q2, and cost inflation (e.g., freight logistics).

• Question from Abigail Eberts (Wells Fargo): Color on HIP businesses exposed to new construction (e.g., stone veneer).
  Response: Strong siding and roofing performance; new strategy driving re-roofing. Infrastructure demand solid from municipalities and data center growth.

• Question from Josh Spector (UBS): Pricing realization in HIP from prior periods and H2 outlook.
  Response: Pricing increases have been pushed through; sequential pricing minor, with all Q2 price largely realized by end of Q2/early Q3.

• Question from Matthew Dioe (Bank of America): Incremental cost cuts from Q1 to Q2 and epoxy tailwind.
  Response: Cost reductions consistent; Q2 saw ~$75M YOY cost of sales reduction despite 10% volume growth. Epoxy benefits from restructuring completed last year and higher-margin segments.

• Question from John Roberts (Mizuho): Revenue size of newly acquired German sites.
  Response: Wilhelmshaven site several hundred million in sales; acquisition to integrate with low-cost US feedstock for European operations.

• Question from Turner Hendricks (Morgan Stanley): Chinese PVC market trends and impact of VAT rebate removal.
  Response: Chinese PVC exports surged pre-VAT removal, then declined; prices rebounded. China remains export base, but NAFTA prices affect competitiveness.

• Question from Frank Mitch (Fermium Research, LLC): Expectation for H2 plant reliability vs. H1 and color on European PVC force majeure.
  Response: Goal to run assets harder in H2; no major turnarounds planned. European force majeure was short-term, minimal impact.

David Bellinger (Docha Bank) - David Bellinger (Docha Bank)

What percentage of polyethylene production was exported in Q2 and H1? - John Roberts (Mizuho)

2025Q3: We have a much higher exposure to export markets, which means we are more directly impacted by global price movements. - [Responder's Name](CEO) (Note: While the 2025Q3 transcript summary does not contain specific quotes, the context of the question about Chinese market trends and export rebates implies a higher level of export exposure and sensitivity, which is contradicted by the specific 10-20% figure given in 2026Q2.)
