Westlake Chemical Partners LP (WLKP) - 2024 Annual Report Summary

Business Context and Reporting Period

This summary covers the Form 10-K for the fiscal year ended December 31, 2024. Westlake Chemical Partners LP is a Delaware limited partnership that operates, acquires, and develops ethylene production facilities. The Partnership's sole revenue-generating asset is its 22.8% limited partner interest in Westlake Chemical OpCo LP ("OpCo"), which owns three ethylene production facilities (Lake Charles Olefins and Calvert City Olefins) and a 200-mile ethylene pipeline. OpCo sells approximately 95% of its ethylene production to Westlake Corporation under a long-term cost-plus agreement, with the remaining volume and co-products sold to third parties.

Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Decline: Total net sales decreased by 4.6% to $1,135.9 million. This was primarily driven by lower ethylene sales prices to Westlake, including the sale of excess quantities at prices excluding certain non-variable costs. This was partially offset by higher sales volumes (+2.0%) and higher third-party ethylene sales prices.
• Profitability Improvement: Despite lower sales, Net Income increased by 10.3% to $369.2 million, and Net Income attributable to the Partnership increased by 15.0% to $62.4 million. Gross margin expanded to 36.9% from 32.5% due to significantly lower ethane feedstock and natural gas costs.
• Cost Reductions: Feedstock (Ethane) costs decreased by 22.6% and Fuel (Natural Gas) costs decreased by 17.3% compared to 2023.
• Turnaround Deferral: The Partnership deferred a planned maintenance turnaround at the Petro 1 facility from Q3 2024 to Q1 2025 to capitalize on higher third-party ethylene prices, resulting in "excess quantities" sold to Westlake at a lower price structure.

Guidance, Outlook, and Risks

• Turnaround Activity: The Petro 1 maintenance turnaround commenced in Q1 2025. Turnarounds typically last 30-60 days and reduce production volumes, impacting cash flow during the period.
• Distributions: The Board declared a quarterly distribution of $0.4714 per unit for Q4 2024, payable February 25, 2025. The Partnership intends to distribute most excess cash generated by operations.
• Debt Structure: All outstanding debt ($399.7 million) is variable-rate, owed to Westlake affiliates, and matures in July 2027. The weighted average interest rate was 6.4% as of year-end. A 100 basis point increase in rates would increase annual interest expense by approximately $4.0 million.
• Key Risks:
  • Concentration Risk: Westlake accounted for 83.7% of net sales in 2024. The Partnership is substantially dependent on Westlake's creditworthiness and ability to meet purchase obligations.
  • Contract Expiration: The Ethylene Sales Agreement and Feedstock Supply Agreement have initial terms through December 31, 2026, with automatic 12-month renewals unless terminated.
  • Operational Hazards: Risks include facility shutdowns, environmental regulations, and labor disputes (a brief strike occurred at Calvert City in November 2024 but ended quickly).

Investor Verification Checklist

• Westlake's Financial Health: Verify Westlake Corporation's ability to meet its minimum purchase commitments under the Ethylene Sales Agreement, as this drives 83.7% of revenue.
• Turnaround Impact: Monitor the execution and cost of the Petro 1 turnaround in Q1 2025 and its effect on production volumes and cash flow.
• Feedstock Pricing: Track ethane and natural gas prices, as lower costs directly improve gross margins under the cost-plus pricing model.
• Debt Covenants: Confirm continued compliance with the MLP Revolver leverage ratio covenants (4.50:1.00 or 5.50:1.00 post-acquisition).
• Contract Renewals: Assess the status of the Ethylene Sales Agreement renewal as the 2026 expiration approaches.
