Westlake Chemical Partners LP reported sharply improved results for the quarter ended March 31, 2026, driven by higher ethylene production and sales to Westlake. Net sales rose to $305.7 million from $237.6 million, while net income nearly doubled to $81.7 million.
Net income attributable to the partnership increased to $14.2 million, or $0.40 per common unit, compared with $0.14 a year earlier. EBITDA grew to $121.2 million, supported by stronger volumes and co-product sales, partially offset by higher natural gas costs.
Operating cash flow increased to $110.2 million, enabling continued quarterly cash distributions of $0.4714 per common unit, even though distributions exceeded net income. The partnership ended the quarter with $44.3 million in cash, $36.4 million invested with Westlake and $399.7 million of variable-rate debt outstanding.
Westlake Chemical Partners LP reported sharply improved first quarter 2026 results. Net income attributable to the Partnership rose to $14.2 million, or $0.40 per limited partner unit, compared to $4.9 million, or $0.14 per unit, in first quarter 2025.
Cash flows from operating activities increased to $110.2 million from $45.8 million a year earlier, driven by higher production and sales volume following the prior year's Petro 1 turnaround. MLP distributable cash flow grew to $17.9 million from $4.7 million.
The Partnership declared a quarterly distribution of $0.4714 per unit, its 47th consecutive quarterly distribution, with a first quarter 2026 coverage ratio of 1.08x and trailing twelve‑month coverage of 1.00x, up from 0.82x at the end of fourth quarter 2025.
Westlake Chemical Partners LP appointed Jonathan H. Baksht, age 51, as Senior Vice President and Chief Financial Officer and as a director of its general partner, effective June 15, 2026. He will also serve as Senior Vice President and Chief Financial Officer of Westlake Corporation, the indirect parent company.
M. Steven Bender, currently Executive Vice President and Chief Financial Officer of the general partner, will retire from the Board of Directors on June 15, 2026 and move into a Special Advisor role to the President, ahead of his previously disclosed retirement by year-end. This reflects a planned leadership transition rather than an abrupt change.
Mr. Baksht brings extensive financial leadership experience, having served as Executive Vice President and Chief Financial Officer of Fortune Brands Innovations, Inc., Chief Financial Officer of Pactiv Evergreen Inc., and Chief Financial Officer of Valaris Limited. The partnership also notes that there are no related-party transactions or family relationships requiring additional disclosure.
Westlake Chemical Partners LP is registering up to $500,000,000 of securities under a shelf prospectus, to be offered from time to time in one or more offerings, subject to completion.

Westlake Chemical Partners files its annual report describing an ethylene-focused partnership structure closely tied to Westlake Corporation. The partnership owns a 22.8% limited partner interest and the general partner of OpCo, whose three U.S. ethylene plants and a 200‑mile pipeline provide about 3.7 billion pounds of annual capacity.
Westlake buys at least 95% of OpCo’s planned ethylene output under a cost‑plus Ethylene Sales Agreement that includes a fixed $0.10‑per‑pound margin and now runs through December 31, 2027, alongside a renewed Feedstock Supply Agreement. This dependence concentrates credit and contract-renewal risk.
The report highlights environmental and climate regulations, potential capital needs for compliance, cybersecurity threats, variable-rate debt exposure, and the conflict-prone governance structure where Westlake controls the general partner. As of December 31, 2025, non‑affiliate common units had an aggregate market value of about $425.6 million, with 35,245,879 common units outstanding as of February 25, 2026.
Westlake Chemical Partners LP reported softer results for 2025, mainly due to its planned Petro 1 turnaround. Fourth-quarter 2025 net income attributable to the Partnership was $14.5 million, or $0.41 per unit, slightly below $15.0 million a year earlier, while operating cash flow fell to $120.4 million from $132.5 million. However, MLP distributable cash flow rose to $18.8 million, giving a strong quarterly coverage ratio of 1.13x.
For full year 2025, net income attributable to the Partnership declined to $48.7 million from $62.4 million, and operating cash flow dropped to $280.5 million from $485.0 million, reflecting turnaround costs and lower volumes. Full-year MLP distributable cash flow was $53.4 million, down from $66.9 million. The Partnership declared a quarterly distribution of $0.4714 per unit, its 46th consecutive payout, and expects higher production and an improved coverage ratio in 2026 with no planned turnarounds.
Westlake Chemical Partners LP announced that M. Steven Bender plans to retire as Executive Vice President and Chief Financial Officer of its general partner and from the general partner’s Board of Directors. His retirement will be effective upon the appointment of his successor as chief financial officer.
The company states that Mr. Bender’s decision to retire was not the result of any disagreement with Westlake Chemical Partners GP LLC or Westlake Chemical Partners LP.
