Westlake Chemical Partners LP

Company Overview

Business Model: Westlake Chemical Partners LP (the Partnership) is a Delaware limited partnership that operates, acquires, and develops ethylene production facilities and related assets. Its business and operations are conducted through Westlake Chemical OpCo LP (OpCo), in which the Partnership holds a 22.8% limited partner interest and 100% of the general partner interest. OpCo generates substantially all of its revenue by selling ethylene to Westlake Corporation and other third parties, as well as through the sale of co-products such as propylene, crude butadiene, pyrolysis gasoline, and hydrogen. A substantial majority of OpCo's planned ethylene production (95%) is sold to Westlake Corporation under a long-term, fee-based Ethylene Sales Agreement, which provides a fixed margin of $0.10 per pound and adjusts for feedstock and natural gas costs, estimated operating costs, and maintenance/turnaround expenditures, less co-product sales proceeds. This structure aims to stabilize cash flow and minimize direct exposure to commodity price fluctuations.

Market Position: OpCo operates three ethylene production facilities with an aggregate annual capacity of approximately 3.7 billion pounds, making it a significant producer of ethylene, the world's most widely used petrochemical. The Ethylene Sales Agreement with Westlake Corporation, a major downstream producer of polyethylene and polyvinyl chloride, provides a stable revenue base for 95% of OpCo's planned production, limiting direct competition for these volumes. For the remaining 5% of planned ethylene and any excess volumes, OpCo competes with regional merchant ethylene producers including LyondellBasell Industries, N.V., Shell Chemical Company, BASF Corporation, and Motiva Enterprises LLC.

Recent Strategic Developments:

• Petro 1 Turnaround Deferral: The planned maintenance turnaround for the Petro 1 production facility was deferred from the third quarter of 2024 to the first quarter of 2025 to maintain production and capitalize on higher average third-party ethylene sales prices during Q3 2024.
• Investment Management Agreement: The Partnership, OpCo, and Westlake Corporation are parties to an Investment Management Agreement authorizing Westlake Corporation to invest excess cash for durations up to nine months, earning a market return plus five basis points, with daily availability for liquidity needs.
• Equity Distribution Agreement (ATM Program): The Partnership has an At-the-Market (ATM) program allowing the sale of common units up to an aggregate offering amount of $50.0 million for general partnership purposes, including funding potential drop-downs and other acquisitions. No common units were issued under this program as of December 31, 2024.

Geographic Footprint: All of the Partnership's assets and operations are located and conducted in the United States. OpCo's ethylene production facilities are situated in Lake Charles, Louisiana (Petro 1 and Petro 2) and Calvert City, Kentucky (Calvert City Olefins). OpCo also owns a 200-mile ethylene pipeline (Longview Pipeline) in Texas. All sales are attributed to the United States.

Leadership Continuity: All executive officers of Westlake Chemical Partners GP LLC (the Partnership's general partner) are employees of Westlake Corporation and allocate their time between the two entities. Westlake Corporation retains ultimate decision-making authority regarding their total compensation.

Board Composition: The general partner's board of directors consists of eight directors. Three directors (G. Stephen Finley, Lisa A. Friel, and Randy G. Woelfel) are independent as defined by NYSE and Exchange Act standards. The board has an audit committee, composed of all three independent directors, with Mr. Finley serving as chairman and all members designated as "audit committee financial experts." A conflicts committee, also comprising the three independent directors with Mr. Woelfel as chair, may be formed to review matters involving potential conflicts of interest.

Business Cyclicality & Seasonality

Demand Patterns:

• Seasonal Trends: Not explicitly detailed in the filing.
• Economic Sensitivity: Demand for ethylene exhibits cyclical commodity characteristics, with margins on ethylene derivative products influenced by the supply-demand balance, operating rates, and general economic activity. The Ethylene Sales Agreement with Westlake Corporation is designed to mitigate the Partnership's direct exposure to these commodity price fluctuations.
• Industry Cycles: The Partnership's ability to execute its growth strategy is, in part, dependent on the demand for ethylene derivatives in the geographical areas served by its ethylene production facilities.

Planning & Forecasting: OpCo implements a strategy of reserving cash annually to cover future turnaround activities, which occur approximately every five to eight years for each ethylene production facility. This approach is intended to reduce the variability in OpCo's cash flow.

Regulatory Environment & Compliance

Regulatory Framework: Industry-Specific Regulations:

• Environmental, Health, and Safety (EHS): The Partnership is subject to extensive federal, state, and local EHS laws and regulations, including the Clean Air Act, Water Pollution Control Act, Resource Conservation and Recovery Act (RCRA), Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and Toxic Substances Control Act (TSCA). Compliance with these laws necessitates capital expenditures and operational changes.
• EPA Regulations: The Partnership is subject to various EPA regulations, including the ethylene Maximum Achievable Control Technology (MACT) rule and National Emission Standards for Hazardous Air Pollutants (NESHAPs), which impose stringent emissions limits, additional leak detection and repair obligations, and performance standards for flares.
• Greenhouse Gas (GHG) Emissions: Operations result in GHG emissions, which are subject to increasing scrutiny and regulation. The EPA requires reporting of GHG emissions from specified large sources and permits for new or modified facilities with significant GHG emissions.
• Climate-Related Disclosures: The Partnership is subject to new U.S. Securities and Exchange Commission (SEC) climate-related disclosure rules (currently stayed due to legal challenges) and California's broader climate-related disclosure mandates.

Trade & Export Controls: The filing mentions general risks related to international trade barriers, tariffs, duties, and violations of international fair trade laws by global competitors, but does not detail specific trade or export control compliance requirements for the Partnership.

Legal Proceedings: The Partnership and OpCo are involved in lawsuits, investigations, and claims, including environmental and employee-related matters, in the ordinary course of business. Management does not believe that any currently pending legal proceedings will have a material adverse effect on the Partnership's business, results of operations, cash flows, or financial condition. Westlake Corporation indemnifies the Partnership for certain environmental and other liabilities that occurred or existed prior to August 4, 2014, under the Omnibus Agreement.

Tax Strategy & Considerations

Tax Profile:

• Effective Tax Rate: 0.23% (2024).
• Geographic Tax Planning: The Partnership is structured as a limited partnership and is treated as a partnership for U.S. federal income tax purposes, meaning it is not liable for entity-level federal income taxes. However, it is subject to state and local income taxes.
• Tax Reform Impact: The present U.S. federal income tax treatment of publicly-traded partnerships, including the Partnership, or an investment in its common units, may be modified by administrative, legislative, or judicial changes or differing interpretations, potentially applied retroactively. Such changes could impact the Partnership's ability to qualify for partnership tax treatment or substantially reduce cash available for distribution.

Insurance & Risk Transfer

Risk Management Framework:

• Insurance Coverage: The Partnership maintains property, business interruption, and casualty insurance coverage, which it believes is in accordance with customary industry practices. However, it acknowledges that it cannot be fully insured against all potential hazards incident to its business, including losses resulting from wars or terrorist acts.
• Risk Transfer Mechanisms: Under the Omnibus Agreement, Westlake Corporation indemnifies the Partnership against certain environmental and other losses that occurred or existed prior to August 4, 2014.
