WLKP

Westlake Chemical Partners LP - 10-Q Summary (Q1 2026)

Business Context and Reporting Period

This report covers the quarterly period ended March 31, 2026. Westlake Chemical Partners LP (WLKP) is a Delaware limited partnership that operates, acquires, and develops ethylene production facilities. The Partnership owns a 22.8% limited partner interest in Westlake Chemical OpCo LP ("OpCo"), which owns three ethylene production facilities and a common carrier pipeline. The remaining 77.2% interest in OpCo is held by Westlake Corporation ("Westlake"). WLKP generates the majority of its revenue through a long-term Ethylene Sales Agreement with Westlake.

Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Net sales increased by $68.1 million (28.7%) driven primarily by higher ethylene production volumes sold to Westlake and increased co-products sales volumes. This contrasts with Q1 2025, which was impacted by the Petro 1 turnaround.
• Profitability: Gross profit margin expanded to 30.7% from 22.8%. Net income attributable to the Partnership increased by $9.3 million (188%) due to higher operational volumes.
• Cost Dynamics: While natural gas costs increased by 33.9% year-over-year, feedstock (ethane) costs decreased by 14.0%. The volume increase offset the higher fuel costs.
• Cash Flow: Operating cash flow surged to $110.2 million from $45.8 million, largely due to higher income from operations and the absence of significant turnaround cash outflows seen in the prior year.
• Capital Expenditures: Additions to property, plant, and equipment decreased to $5.6 million from $16.0 million, reflecting the completion of the Petro 1 turnaround in the prior year.

Guidance, Outlook, and Risks

• Distributions: The General Partner declared a quarterly distribution of $0.4714 per common unit, payable June 1, 2026. This amount did not exceed the threshold for Incentive Distribution Rights (IDR) payments.
• Liquidity: The Partnership maintains $44.3 million in cash and $36.4 million invested under the Investment Management Agreement with Westlake. It has access to two revolving credit facilities (OpCo Revolver and MLP Revolver) totaling $1.2 billion capacity, with $399.7 million currently outstanding.
• Outlook: Management expects to distribute most excess cash generated. Future expansion capital expenditures are expected to be funded by loans from Westlake, though Westlake is under no obligation to provide such funding.
• Risks: Key risks include the cyclical nature of the chemical industry, volatility in raw material and energy prices, and reliance on Westlake for feedstock supply and product sales (Westlake accounted for 86.1% of net sales in Q1 2026). Environmental liabilities and potential operating interruptions (turnarounds) also pose risks.

Investor Verification Checklist

• Related Party Dependence: Verify the stability of the Ethylene Sales Agreement and Feedstock Supply Agreement with Westlake, given that 86.1% of revenue and a significant portion of costs are related-party transactions.
• Turnaround Schedule: Confirm the timing of future major maintenance turnarounds for the Lake Charles and Calvert City facilities, as these significantly impact quarterly cash flows and production volumes.
• Debt Covenants: Review the Consolidated Leverage Ratio covenants under the MLP Revolver (maximum 4.50:1.00) to ensure compliance given the current debt load of ~$400 million.
• Commodity Exposure: Assess the impact of rising natural gas prices on margins, noting that while the contract is cost-plus, higher input costs can affect working capital requirements.
• Noncontrolling Interest: Understand that the majority of consolidated net income ($67.5 million in Q1 2026) is attributable to Westlake's noncontrolling interest in OpCo, not the public unitholders.
