    Segment performance

    4
    SegmentRevenueYoYQoQMargin
    Housing and Infrastructure Products (HIP)
    Q4 sales declined 8% year-over-year, driven by a decrease in sales volumes, primarily in PVC compounds and exterior building products due to lower residential construction activity. This was partially offset by solid municipal pipe sales. EBITDA margin was 16% in Q4 2025, below the prior year due to unfavorable sales mix and higher costs.
    -8%16%
    Housing and Infrastructure Products (HIP)
    Full year 2025 EBITDA of $839 million and EBITDA margin of 20% were in line with guidance. The segment managed the slower new residential construction environment well due to its broad geographical footprint and product offering, supported by strong customer adoption of innovative PVCO pipe and municipal pipe demand.
    EBITDA Margin: 20%
    $839 million EBITDA
    Performance and Essential Materials (PEM)
    Q4 EBITDA decreased by $45 million from Q3 2025, driven by 5% lower average sales price (polyethylene, PVC resin) and 2% lower sales volume (seasonal customer inventory destocking). Partially offset by a $27 million pension benefit and $26 million benefit from lower planned turnarounds. Global overcapacity continued to pressure profitability.

    $45 million EBITDA
    Performance and Essential Materials (PEM)
    Full year 2025 EBITDA was lower than 2024 due to higher feedstock and energy costs, elevated planned/unplanned outages, and lower global sales prices. Weak global industrial manufacturing activity and overseas capacity additions created overcapacity, particularly in polyethylene and chlor-alkali/chlorovinyls.

    Lower new housing construction activity in North AmericaQ4 FY25 and expected for FY26

    HIP Q4 sales declined 8% YoY; Housing starts forecast 1.3M-1.4M in 2026 (similar to 2025)

    Mitigation: Diversified product offering, broad geographical footprint, strong municipal pipe sales, and product innovation (e.g., PVCO pipe) to maintain market position and capitalize on affordability improvements.

    Elevated feedstock and energy costs, and high levels of planned/unplanned outages in PEMFY25, but expected to improve in FY26

    Why it matters

    Plant reliability is a key pillar of the company's $600M earnings improvement strategy, directly impacting PEM's profitability.

    The third pillar is reliability. And of course, we have to earn that each and every day but we're very confident we've made significant investments in our plants, significant training of our people. '24 and '25 were years of very elevated levels of planned turnarounds and therefore, associated with some of those planned turnarounds where the unplanned outages as we brought those plants up or attempted to. 2026 will be a year with far fewer planned turnarounds. So we do have a high expectation that we'll be able to deliver on that third pillar of reliability.

    Q&A highlights

    7

    Can you break down the PEM Q4 beat against the mid-December announcement of roughly $90 million?

    The beat was attributed to proactive steps from the 3-pillar initiative, specifically removing losses from sales in low-priced export markets by shuttering assets, and initial cost reduction initiatives at the end of 2025. Pension benefits annuitization also contributed.

    the beat was really attributable to beginning to take the proactive steps in our 3-pillar initiative by removing the losses that we saw accruing from those sales in that low-priced market and begin to take some of those cost reduction initiatives at the tail end of 2025.

    Detailed Narrative

    01

    Strategic Restructuring and Cost Optimization

    Westlake undertook decisive actions in Q4 FY25 to restructure its businesses and reset its cost position, addressing persistent macroeconomic challenges🌐. This included writing off $495 million in inventory and accruing expenses for the closure of 1 styrene, 3 chlorovinyl facilities in North America, and an epoxy facility in Pernis, Netherlands. Additionally, $16 million was accrued for HIP footprint optimization and a compounding business sale. These actions, totaling $511 million, are expected to contribute significantly to the company's 3-pillar strategy for earnings improvement in 2026.

    02

    3-Pillar Strategy for 2026 Earnings Improvement

    The company outlined a 3-pillar strategy aimed at delivering $600 million in gross earnings improvement for 2026. The first pillar, footprint optimization, is expected to yield $200 million by closing higher-cost PEM assets and HIP fabrication sites. The second pillar focuses on improving plant reliability, targeting a $200 million year-over-year EBITDA improvement. The third pillar involves an additional structural company-wide cost reduction program, building on FY25's success, to deliver another $200 million in 2026. These initiatives are designed to create a more competitive and efficient operating model.

    03

    HIP Segment Resilience Amidst Housing Slowdown

    The Housing and Infrastructure Products (HIP) segment demonstrated stability in Q4 FY25 despite a seasonal decline in sales volume and lower new housing construction activity in North America, resulting in an 8% YoY sales decline. The segment's full-year 2025 EBITDA of $839 million and 20% margin were in line with expectations, supported by strong municipal pipe sales volumes due to infrastructure spending. HIP's broad geographical footprint and product offerings, including innovative PVCO pipe, helped it manage the slower residential construction environment better than the overall industry.

    04

    PEM Segment Challenges and Strategic Adjustments

    The Performance and Essential Materials (PEM) segment continued to face significant challenges in Q4 FY25, with a 5% sequential decline in average sales prices and a 2% lower sales volume. Global overcapacity, particularly in polyethylene and chlorovinyls, led to margin compression and a Q4 EBITDA of $45 million, down $45 million QoQ. In response, Westlake made the strategic decision to close non-integrated and higher-cost North American chlorovinyl assets, expecting an annual EBITDA benefit of $100 million starting in 2026 by reducing exposure to low-priced export markets.

    05

    Market Outlook and Demand Signals

    Management expressed cautious optimism for 2026, citing signs of improvement in global industrial and manufacturing activity. The January U.S. ISM reading of 53 marked the first month in expansionary territory in a year, and the average 30-year mortgage rate dropped to 6.2%, improving housing affordability. These factors suggest potential sales volume growth in both segments for 2026, with a forecast of 1.3 million to 1.4 million housing starts. The company also noted early signs of restocking and price traction in PVC and caustic soda markets.

    06

    Balance Sheet Strength and Capital Allocation

    Westlake maintains a strong financial position with $2.9 billion in cash and securities and total debt of $5.6 billion as of December 31, 2025, with a 16-year average debt maturity life. The company returned $335 million to shareholders in FY25 through dividends and share repurchases. For 2026, capital expenditures are projected to be $900 million, a $100 million reduction year-over-year. The focus remains on strategic deployment of capital to create long-term shareholder value, with near-term opportunities predominantly in the HIP segment.
