Material Changes vs. Prior Period
- Revenue: Q2 2025 net sales increased 4.5% year-over-year, driven by higher ethylene sales prices (+9.1% impact) and a $13.6 million buyer deficiency fee recognized due to a forecasted production shortfall. This was partially offset by a 9.3% volume decrease due to the Petro 1 turnaround.
- Profitability: Gross profit margins declined to 32.8% in Q2 2025 from 35.6% in Q2 2024, primarily due to significantly higher ethane feedstock (+25.2%) and natural gas (+80.2%) costs.
- Cash Flow: Net cash provided by operating activities dropped to $54.9 million for the six months ended June 30, 2025, compared to $226.5 million in the prior year period. This decrease was driven by cash used for the Petro 1 turnaround and lower operating income.
- Capital Expenditures: Capital expenditures doubled to $40.3 million in the first six months of 2025 compared to $20.0 million in 2024, largely due to the Petro 1 turnaround maintenance.
Guidance, Outlook, and Risks
- Turnaround Status: The planned maintenance turnaround for the Petro 1 facility commenced in January 2025 and concluded in April 2025. The extension of this turnaround into April (vs. a planned March completion) resulted in the recognized buyer deficiency fee.
- Distributions: On July 30, 2025, the General Partner declared a quarterly distribution of $0.4714 per common unit, payable August 27, 2025. This distribution did not exceed the threshold for Incentive Distribution Rights (IDR) payments.
- Liquidity: The Partnership maintains $36.6 million in cash and cash equivalents, plus $43.9 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 in capacity, with $399.7 million currently outstanding.
- Risks: Key risks include the cyclical nature of the chemical industry, volatility in feedstock and energy prices, and reliance on Westlake Corporation for 90.6% of sales (Q2 2025). The Partnership is also subject to environmental regulations and potential liabilities, though it is indemnified by Westlake for pre-IPO liabilities.
Investor Verification Checklist
- Buyer Deficiency Fee Timing: Verify the expected collection date for the $13.6 million deficiency fee, as the filing notes payment is scheduled after December 31, 2025.
- Feedstock Cost Sustainability: Assess the sustainability of the 25%+ increase in ethane costs and 80%+ increase in natural gas costs and their impact on future margins.
- Turnaround Reserve Adequacy: Confirm that the cash reserves and pricing mechanisms in the Ethylene Sales Agreement are sufficient to cover future turnaround costs without impacting distribution coverage.
- Debt Covenants: Review the Consolidated Leverage Ratio to ensure compliance with the MLP Revolver covenants (4.50:1.00 or less), especially given the variable interest rate exposure.
- Related Party Concentration: Acknowledge the extreme concentration risk with Westlake Corporation, which accounts for the vast majority of sales and provides all operating services and debt financing.
