Westlake Chemical Partners LP Announces Second Quarter 2025 Results

•Declared quarterly distribution of $0.4714 per unit; 44th consecutive quarterly distribution

HOUSTON--(BUSINESS WIRE)--Westlake Chemical Partners LP (NYSE: WLKP) (the "Partnership") today reported net income attributable to the Partnership in the second quarter of 2025 of $14.6 million, or $0.41 per limited partner unit, which was in line with second quarter 2024 net income of $14.4 million. Cash flows from operating activities in the second quarter of 2025 were $9.1 million, a decrease of $112.8 million compared to second quarter 2024 cash flows from operating activities of $121.9 million. For the three months ended June 30, 2025, MLP distributable cash flow was $15.0 million, a decrease of $2.1 million compared to second quarter 2024 MLP distributable cash flow of $17.1 million. The decrease in MLP distributable cash flow and associated trailing twelve-month coverage ratio was primarily due to higher maintenance capital expenditures as a result of the Petro 1 turnaround.

Compared to the first quarter of 2025, second quarter 2025 net income attributable to the Partnership of $14.6 million increased by $9.7 million due to higher production and sales volume as a result of fewer production days impacted by the Petro 1 turnaround. Second quarter 2025 cash flows from operating activities of $9.1 million decreased by $36.7 million compared to first quarter 2025 cash flows from operating activities of $45.8 million due to the timing of cash payments related to the Petro 1 turnaround. Second quarter 2025 MLP distributable cash flow of $15.0 million increased by $10.3 million compared to first quarter 2025 MLP distributable cash flow of $4.7 million, due to higher production and sales volume as a result of fewer production days impacted by the Petro 1 turnaround.

Second quarter 2025 consolidated net income, including OpCo's earnings, of $85.8 million increased from first quarter 2025 consolidated net income of $42.3 million. During the second quarter of 2025, OpCo benefitted from the stability of its sales agreement with Westlake Corporation that provides a fixed margin on OpCo's annual ethylene production plan. As a result of this agreement, OpCo's net income benefitted by $13.6 million to offset lower forecasted annual production volume resulting from the extension of the Petro 1 turnaround into April.

"The Partnership's second quarter financial results improved significantly from the first quarter of 2025 due to higher production and sales volume at our Petro 1 facility as a result of fewer production days lost to the turnaround that began at the end of January and lasted until early April. While there were some lingering impacts to distributable cash flow in the second quarter from the extension of the turnaround into April, primarily in the form of elevated maintenance capital expenditures, this was not unexpected and should not re-occur at such a high level in future quarters," said Jean-Marc Gilson, President and Chief Executive Officer. "Looking ahead, we expect distributable cash flow and the associated coverage ratio to solidly improve in the second half of 2025 back towards our strong historical levels now that the Petro 1 turnaround has been completed."

On July 30, 2025, the Partnership announced that the Board of Directors of Westlake Chemical Partners GP LLC had approved a quarterly distribution for the second quarter of 2025 of $0.4714 per common unit to be payable on August 27, 2025 to unitholders of record as of August 12, 2025, representing the 44th consecutive quarterly distribution to our unitholders. MLP distributable cash flow provided trailing twelve-month coverage that was 0.79x the declared distributions for the second quarter of 2025, which was below the trailing twelve-month coverage ratio of 0.82x at the end of the first quarter of 2025 due to the planned Petro 1 turnaround. Since our IPO in July of 2014 our cumulative coverage ratio is approximately 1.05x.

OpCo's Ethylene Sales Agreement with Westlake is designed to provide for stable and predictable cash flows. The agreement provides that 95% of OpCo's ethylene production is sold to Westlake for a cash margin of $0.10 per pound, net of operating costs, maintenance capital expenditures and reserves for future turnaround expenditures.

i

The statements in this release and the related teleconference relating to matters that are not historical facts, such as those with respect to timing and success of future turnarounds, our expectations regarding the amount and timing of future capital expenditures, the ability to deliver value, returns, predictable cash flows and distributions to unitholders, the expectation that distributable cash flow and the associated coverage ratio will improve in the second half of 2025, and the nature and stability of the sales agreement with Westlake and the margin under that agreement, are forward-looking statements. These forward-looking statements are subject to significant risks and uncertainties. Actual results could differ materially, based on factors including, but not limited to, pandemic infectious diseases and the response thereto; operating disruptions, including delays in turnaround activities; the volume of ethylene that we are able to sell; the price at which we are able to sell ethylene; changes in the price and availability of feedstocks; changes in prevailing economic conditions; actions and commitments of Westlake, including the renewal or renegotiation of, or determinations made pursuant to, our contractual arrangements with Westlake; actions of third parties; inclement or hazardous weather conditions, including flooding, and the physical impacts of climate change; environmental hazards; changes in laws and regulations (or the interpretation thereof); inability to acquire or maintain necessary permits; inability to obtain necessary production equipment or replacement parts; technical difficulties or failures; labor disputes; difficulty collecting receivables; inability of our customers to take delivery; fires, explosions or other industrial accidents; our ability to borrow funds and access capital markets; and other factors. For more detailed information about the factors that could cause actual results to differ materially, please refer to the Partnership's Annual Report on Form 10-K for the year ended December 31, 2024, which was filed with the SEC in March 2025, and the Partnership's Quarterly Report on Form 10-Q for the quarter ended March 31, 2025, which was filed with the SEC in May 2025.

This release is intended to be a qualified notice under Treasury Regulation Section 1.1446-4(b). Brokers and nominees should treat one hundred percent (100.0%) of the Partnership's distributions to non-U.S. investors as being attributable to income that is effectively connected with a United States trade or business. Accordingly, the Partnership's distributions to non-U.S. investors are subject to federal income tax withholding at the highest applicable effective tax rate.

Use of Non-GAAP Financial Measures

This release makes reference to certain "non-GAAP" financial measures, such as MLP distributable cash flow, coverage ratio and EBITDA. For this purpose, a non-GAAP financial measure is generally defined by the Securities and Exchange Commission ("SEC") as a numerical measure of a registrant's historical or future financial performance, financial position or cash flows that (1) excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the most directly comparable measure calculated and presented in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") in the statement of operations, balance sheet or statement of cash flows (or equivalent statements) of the registrant; or (2) includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the most directly comparable measure so calculated and presented. We report our financial results in accordance with U.S. GAAP, but believe that certain non-GAAP financial measures, such as MLP distributable cash flow, coverage ratio and EBITDA, provide useful supplemental information to investors regarding the underlying business trends and performance of our ongoing operations and are useful for period-over-period comparisons of such operations. These non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, the financial measures prepared in accordance with U.S. GAAP. We define MLP distributable cash flow as distributable cash flow less distributable cash flow attributable to Westlake Corporation's noncontrolling interest in OpCo and distributions attributable to the incentive distribution rights holder. MLP distributable cash flow does not reflect changes in working capital balances. We define EBITDA as net income before interest expense, income taxes, depreciation and amortization. MLP distributable cash flow, coverage ratio and EBITDA are non-GAAP supplemental financial measures that management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, may use to assess our operating performance as compared to other publicly traded partnerships, our ability to incur and service debt and fund capital expenditures and the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities. Reconciliations of MLP distributable cash flow to net income and to net cash provided by operating activities and of EBITDA to net income, income from operations and net cash provided by operating activities can be found in the financial schedules at the end of this press release.
