What are the expectations for HIP in Q2, given the lag between rising PVC/transportation costs and the ability to pass through pricing? How did April perform, and what does the order book look like?

Steve Bender stated that the order book for Q2 looks very good for volumes. However, there could be a 1-2 month lag in Q2 for price realization to fully offset higher PVC resin and transportation costs, leading to some headwind in the first half of Q2. Full benefit expected in Q3. “there could be a month or 2 lag between the realization of those price nominations that we've made in the market and the roll forward of PVC resin prices. So there could be some headwind in that second quarter.”

Given the $0.30 increase in April, what is the confidence level for achieving the announced $0.20 per pound increase for May?

Jean-Marc Gilson noted that the $0.30 increase was achieved in April. It's early in May, but the market has absorbed significant increases previously (e.g., 2021). They are watching demand but still pushing for price increases reflective of the market. “we certainly have been able to achieve that $0.30, as you noted in April, and it's still early days in May.”

Qualitative commentary on PEM operating rates in Q1 and so far in Q2.

Steve Bender stated that polyethylene business is running at full rates due to strong demand. PVC operating rates were in the mid-80s in Q1 and are expected to elevate in Q2/Q3 due to construction season and optimized footprint. “In the polyethylene business, we're running full rates... operating rates in the PVC space were in the mid-80s.”

Executive summary

Westlake Corporation Q1 FY26 — Middle East Conflict Drives PEM Sales and Margin Expansion

Westlake Corporation navigated a challenging Q1 FY26, with significant improvements in its PEM segment driven by global supply disruptions from the Middle East conflict, leading to higher prices and margins for its North American-advantaged assets. The company's 3-pillar profitability plan contributed substantial EBITDA uplift, though the HIP segment faces near-term headwinds from a slower homebuilding season and cost pass-through lags. Management remains focused on cost discipline and strategic capital allocation amidst a fluid global environment.

Highlights

Delivered $2.7 billion in net sales and $235 million in EBITDA, supported by customer supply needs and cost management.
PEM segment saw significant improvement in sales volume and earnings towards quarter-end, driven by Middle East conflict-related supply disruptions, leading to 3% sequential volume growth (excluding 2025 plant shutdowns).
3-pillar profitability improvement plan delivered approximately $150 million of EBITDA uplift, returning Epoxy business to profitability.
HIP segment delivered 10% sequential sales volume growth (excluding ACI acquisition), driven by infrastructure and seasonally stronger residential demand.
Strong balance sheet with $2.5 billion cash and investments and $5.6 billion total debt, providing financial flexibility for growth initiatives.

Concerns

Reported a net loss of $100 million or $0.77 per share in Q1 FY26, compared to a net loss of $33 million in Q1 FY25.
HIP segment revenue and EBITDA margin expected to be towards the lower end of the previously communicated range ($4.4B-$4.6B revenue, 19%-21% EBITDA margin) due to slower homebuilding season and increased transportation/raw material costs.
PEM segment faced a $45 million EBITDA headwind from 34% higher North American natural gas prices in January and February.
PVC resin average sales price declined sequentially from Q4 FY25 due to late 2025 price resets, despite a favorable mix shift.
Potential for 1-2 month lag in HIP segment to pass through higher PVC resin and transportation costs, creating a near-term headwind in Q2.

Risks & headwinds

Slower-than-expected homebuilding season 2026

HIP revenue and EBITDA margin expected to be towards the lower end of previously communicated range ($4.4B-$4.6B revenue, 19%-21% EBITDA margin)

Mitigation:HIP continues to benefit from diversified product offering and broad national distribution.

Increased transportation and raw material costs Near term

Particularly for PVC resin, impacting HIP segment

Mitigation:Expect to pass these cost increases through, but timing could create a headwind.

Lag in passing through cost increases in HIP Q2 FY26

1-2 month lag between cost increases and price realization

Mitigation:Price increases have been announced to offset costs; full benefit expected in Q3.

Elevated North American natural gas prices January and February of Q1 FY26

$45 million EBITDA headwind for PEM

Mitigation:Natural gas prices declined by end of March, not expected to impact Q2 earnings.

Middle East conflict supply disruptions Throughout 2026 or beyond

Could persist throughout 2026

Mitigation:Westlake's North American advantaged asset footprint positions it to benefit from pricing momentum.

Uncertainty in North American new residential construction market Near-term

Forward-looking indicators such as single-family housing permits and starts add to the uncertainty

Mitigation:Pipe and fittings business continues to deliver double-digit sales volume growth supported by infrastructure spending and data center build-out.

$67 million settlement for direct purchasers component; $10 million reserve for second category of claimants

Mitigation:In conversation with other categories of claimants.

What to watch in Q2 FY26

HIP segment margin recovery

Q3 FY26

Current slight decline in EBITDA margin in Q1 FY26, potential 1-2 month lag in Q2

Target Recovery towards the guided 19%-21% range, with full benefit of price increases

Why it matters

Indicates the effectiveness of price pass-through and the impact of housing market dynamics on profitability.

I think we get the full benefit of all that in the third quarter, but the fourth quarter typically has a seasonal slowdown just because of the weather dynamics and is typically 1 of our lower margin and volume quarters.

Q&A highlights

Why were PEM results down sequentially despite profitability plan benefits and rising PE/caustic prices? Specifically, what was the headwind from PVC price/margin declines and any other operational issues?

Steve Bender explained that price resets in late 2025 impacted PVC average sales prices, and elevated natural gas costs in Jan/Feb created a $45 million EBITDA headwind. While reliability improved, full value capture from PVC price increases was not realized across the entire quarter.

“the increase that we've seen in PVC resin have not been fully catching up with some of the increases that we've seen in associated costs, especially, I would note the elevated natural gas cost that we saw in January and February.”

Detailed narrative

Impact of Middle East Conflict on PEM Segment

The Middle East conflict significantly disrupted global polyethylene (10-15% of global supply) and PVC (5% of global supply) markets, alongside 20% of global oil supply, reducing chemical feedstock availability. This dynamic steepened the global cost curve, benefiting Westlake's cost-advantaged North American assets and driving increased demand and prices for its products, particularly in March. Management expects these supply disruptions to persist throughout 2026.

Progress on 3-Pillar Profitability Improvement Plan

Westlake's 3-pillar profitability improvement plan delivered approximately $150 million in EBITDA uplift during Q1 FY26. This included significant fixed cost reductions in the PEM segment and successfully returning the Epoxy business to profitability, which had previously incurred over $100 million in annual EBITDA losses. The company remains confident in achieving its targeted $600 million EBITDA uplift for the full year 2026.

HIP Segment Performance and Outlook Adjustment

The Housing and Infrastructure Products (HIP) segment experienced initial headwinds from unusually cold weather in January and February, but performance improved in March. The segment achieved 10% sequential sales volume growth (excluding the ACI acquisition). However, the full-year outlook for HIP revenue and EBITDA margin was adjusted to the lower end of previous guidance due to a slower-than-expected homebuilding season and rising transportation and raw material costs, particularly for PVC resin.

PEM Segment Dynamics and Natural Gas Costs

The PEM segment's Q1 EBITDA was negatively impacted by a $45 million headwind due to 34% higher North American natural gas prices in January and February. However, natural gas prices declined by the end of March to their lowest levels since 2024.

The segment saw improved price realization for olefins, polyethylene, and caustic soda towards the quarter's end, with polyethylene operating at full rates and PVC rates in the mid-80s, expected to increase.

Strategic Acquisitions and Financial Strength

Westlake maintains a strong financial position with $2.5 billion in cash and investments and $5.6 billion in total debt as of March 31, 2026. The company is actively pursuing strategic growth initiatives, including the recent acquisition of ACI, which strengthened its position in the high-voltage wire and cable market.

Additionally, Westlake has entered a non-binding letter of intent to acquire a PVC and VCM plant in Germany, leveraging its advantageous logistical infrastructure.

PVC Market and Chinese Export Dynamics

Management noted that 25-30% of Chinese PVC capacity, being naphtha-based, is now uncompetitive due to high naphtha prices, leading to reduced production. The removal of the 15% VAT export drawback in China further increases the hurdle for exporters. While PVC export prices spiked over $1,000 per ton and then stabilized around $850-$900 per metric ton, they remain significantly higher than last year, suggesting an elevated price environment for an extended period.
