Business Commentary:

Financial Performance and Restructuring:

• Westlake Corporation reported a net loss of $33 million or a loss of $0.25 per share in the fourth quarter with sales of $2.5 billion. The company also noted a decline in full-year 2025 sales by 8% to $11.2 billion.
• The financial challenges were attributed to a 5% decline in sales volume and a 3% decline in average sales price, primarily driven by lower new housing construction activity and global overcapacity in certain products, particularly in PVC resin and epoxy resin.

Cost Reduction and Efficiency Improvements:

• Westlake achieved over $170 million in structural cost reductions in 2025 and anticipates an additional $200 million in cost savings in 2026.
• These reductions are part of a strategic plan to address macroeconomic challenges and include actions such as closing higher-cost assets and optimizing plant operations for improved reliability.

Segment Performance in Housing and Infrastructure Products (HIP):

• HIP segment sales declined 8% year-over-year in Q4, driven by a decrease in sales volumes, particularly in PVC compounds and exterior building products.
• Despite lower residential construction activity, HIP maintained stable performance due to strong customer adoption of innovative products like PVCO pipe and continued demand for municipal pipe.

Polyethylene and Chlorovinyls Market Conditions:

• The Performance and Essential Materials (PEM) segment saw a 5% decline in average sales prices for polyethylene and PVC resin in Q4, contributing to a decrease in EBITDA margin.
• Global overcapacity and weak industrial manufacturing activity were key factors impacting the segment's profitability, prompting strategic asset closures to mitigate exposure to low-priced export markets.

Outlook and Strategic Initiatives for 2026:

• Westlake's 3-pillar strategy is expected to contribute $600 million of improvement in earnings in 2026, focusing on footprint optimization, cost reduction, and operational reliability.
• The company anticipates a rebound in demand, supported by improved housing affordability and expects sales volume growth across segments, positioning itself for stronger future performance.

Sentiment Analysis:

Overall Tone: Positive

• Management expects '2026 represents an inflection point' and is 'cautiously optimistic' due to actions taken to optimize footprint, cost savings, and signs of improvement in housing and industrial demand. The 3-pillar strategy is expected to deliver $600M earnings growth.

Q&A:

• Question from David Begleiter (Deutsche Bank): Can you go back to the HIP business in Q4 and break down the beat versus what you announced back in mid-December of roughly $90 million?
  Response: The beat was attributable to proactive 3-pillar initiatives, including removing losses from shuttered low-price market assets and implementing cost reductions.

• Question from David Begleiter (Deutsche Bank): What are your expectations around your announced price increases and potential realization?
  Response: Some price increases in polyethylene have been made, with further announcements planned, aiming to offset prior non-market adjustments.

• Question from Patrick Cunningham (Citi): How would you frame the supply and demand outlook and direction from price and margin in 2026 for chlorovinyl and PVC chain?
