Current report

For taxable years beginning after December 31, 2024, the OBBBA modifies the limitation on the deduction of business interest by providing that adjusted taxable income is calculated before deductions for depreciation, amortization and depletion. Prior to the OBBBA's passage, for taxable years beginning on or after January 1, 2022, adjusted taxable income was calculated after taking such deductions into account. The OBBBA also extends the limitation to interest that is required to be capitalized under the Code, subject to certain exceptions.
Removed paragraphs (1)

Previous report

In general, we are entitled to a deduction for interest paid or accrued on indebtedness properly allocable to our trade or business during our taxable year. However, our deduction for "business interest" is limited to the sum of our business interest income and 30% of our "adjusted taxable income." For the purposes of this limitation, our adjusted taxable income is computed without regard to any business interest expense or business interest income. In the case of taxable years beginning on or after January 1, 2022, our adjusted taxable income is computed by taking into account any deduction allowable for depreciation, amortization, or depletion.

•Cost reimbursements due to our general partner and Westlake for services provided to us or on our behalf reduce our earnings and therefore our cash available for distribution to our unitholders. The amount and timing of such reimbursements are determined by our general partner.

Current wording

•We are obligated to reimburse our general partner and Westlake for services provided to us or on our behalf, which may reduce our earnings and therefore our cash available for distribution to our unitholders. The amount and timing of such reimbursements are determined by our general partner.

Previous wording

Westlake may be unable to generate enough cash flow from operations to meet its minimum obligations under the Ethylene Sales Agreement if its business is adversely impacted by competition, operational problems, international trade barriers, general adverse economic conditions or the inability to obtain feedstock. For example, lower prices of crude oil could lead to a reduction in the cost advantage for natural gas liquids-based ethylene derivatives in North America, such as Westlake's, as compared to naphtha-based ethylene derivatives. Additionally, Westlake operates internationally and could be adversely affected by trade barriers, tariffs and duties, or violations of international fair trade laws by global competitors. As a result, Westlake's margins and cash flows could be negatively impacted during such period. If Westlake is not able to meet its minimum payment obligations to OpCo as a result of any one or more of these factors, our ability to make distributions to our unitholders would be reduced or eliminated. The amount paid by Westlake will depend upon its ability to satisfy its minimum obligations under the Ethylene Sales Agreement and its ability and election to increase volumes above the minimums specified in the Ethylene Sales Agreement, which in turn are dependent upon, among other things, the level of polyethylene and polyvinyl chloride production at Westlake's other facilities, as well as industry capacity expansion in these downstream products in North America, a number of which have been recently completed. If Westlake is unable to generate sufficient cash flow from its operations to meet its obligations, or otherwise defaults on its obligations, under the Ethylene Sales Agreement, OpCo will not have sufficient available cash to distribute to us to enable us to pay the minimum quarterly distribution set forth in our cash distribution policy. As a result, our ability to pay the minimum quarterly distribution is based on the following factors, some of which are beyond our control:

Westlake's obligations under the Ethylene Sales Agreement, the Feedstock Supply Agreement and the related Services and Secondment Agreement continue in effect until December 31, 2026, after which such agreements will extend on an annual basis unless and until terminated by either party upon at least 12 months' prior written notice. If OpCo were unable to reach agreement with Westlake on an extension or replacement of these agreements, then our ability to make distributions on our common units could be materially adversely affected and the value of our common units could decline.

In October 2025, OpCo and Westlake agreed to renew both the Ethylene Sales Agreement and the Feedstock Supply Agreement through December 31, 2027 in accordance with their respective terms. If OpCo were unable to reach agreement with Westlake on an extension or replacement of these agreements in the future, then our ability to make distributions on our common units could be materially adversely affected and the value of our common units could decline.

Previous wording

Additionally, certain of Westlake's employees in North America are represented by labor unions and works councils. Our operations may be adversely affected by strikes, work stoppages and other labor disputes involving those employees that operate and maintain OpCo's ethylene production facilities and other assets. For example, on November 1, 2024, bargaining unit employees of Local Lodge No. 2781 of the IAM began a strike at our Calvert City, Kentucky facility, after the IAM members did not accept Westlake's final offer for a new collective bargaining agreement. The strike ended on November 8, 2024, after the IAM accepted Westlake's offer for a new collective bargaining agreement. Any future strikes or work stoppages could be significant and have an adverse effect on our financial condition and results of operations.

Our strategy to grow our business and increase distributions to unitholders is dependent on our ability to make acquisitions that result in an increase in our cash distributions per unit. If we are unable to make acquisitions of additional interests in OpCo from Westlake on acceptable terms or we are unable to obtain financing for these acquisitions, our future growth and ability to increase distributions will be limited. In addition, we may be unable to make acquisitions from third parties as an alternative avenue to growth. Furthermore, even if we do consummate acquisitions that we believe will be accretive, they may in fact result in a decrease in our cash distributions per unit. Any acquisition involves potential risks, some of which are beyond our control, including, among other things:

Our operations also produce greenhouse gas ("GHG") emissions, which have been the subject of increased scrutiny and regulation. In December 2015, the United States joined the international community at the 21st Conference of the Parties of the United Nations Framework Convention on Climate Change in Paris, France. The resulting Paris Agreement calls for the parties to undertake "ambitious efforts" to limit the average global temperature and to conserve and enhance sinks and reservoirs of greenhouse gases. The United States signed the Paris Agreement in April 2016, and the Paris Agreement went into effect in November 2016. In November 2019, the United States submitted formal notification to the United Nations that it intended to withdraw from the Paris Agreement. The withdrawal took effect in November 2020. However, President Biden signed an executive order on January 20, 2021 for reentry of the United States into the Paris Agreement and on February 19, 2021, President Biden formally rejoined the Paris Agreement. As part of rejoining the Paris Agreement, President Biden announced that the United States would commit to a 50 to 52 percent reduction from 2005 levels of GHG emissions by 2030 and set the goal of reaching net-zero GHG emissions by 2050. To measure progress towards this target, the Paris Agreement requires the parties to complete a global stocktake, assessing members' collective efforts and achievements in reducing GHG emissions and adapting to the impacts of climate change, every five years. On December 13, 2023, the 28th annual United Nations Climate Change Conference ("COP 28"), which was held in Dubai, issued its first global stocktake, which calls on parties, including the United States, to contribute to the transitioning away from fossil fuels, reduce methane emissions, and increase renewable energy capacity, among other things, to achieve net zero emissions by 2050. In January 2025, the United States submitted formal notification to the United Nations that it intends to withdraw from the Paris Agreement. Pursuant to the terms of the Paris Agreement, the withdrawal will take effect in January 2026.

In January 2025, the United States submitted formal notification to the United Nations of its intention to withdraw from the Paris Agreement. Pursuant to the terms of the Paris Agreement, the withdrawal took effect in January 2026.

Previous wording

On March 6, 2024, the U.S. Securities and Exchange Commission ("SEC") adopted a new set of rules that require a wide range of climate-related disclosures, including material climate-related risks, information on any climate-related targets or goals that are material to the registrant's business, results of operations, or financial condition, Scope 1 and Scope 2 GHG emissions on a phased-in basis by certain larger registrants when those emissions are material and the filing of an attestation report covering the same, and disclosure of the financial statement effects of severe weather events and other natural conditions including costs and losses. Multiple lawsuits have been filed challenging the SEC's new climate rules, and on April 4, 2024, the SEC issued an order staying the final rules until judicial review is complete. In September 2023, California passed climate-related disclosure mandates that are broader than the SEC's rules. As our chemical processing results in GHG emissions, these and other environmental disclosure laws and regulations could affect our costs of doing business.

Previous wording

Westlake has publicly announced a target 20% reduction in its Scope 1 and Scope 2 CO2 equivalent emissions intensity per ton of production by 2030 from a 2016 baseline. Developing and implementing plans for compliance with voluntary climate commitments can lead to additional capital, personnel, operations and maintenance expenditures and could significantly affect the economic position of existing facilities and proposed projects. Westlake's failure or perceived failure to pursue or fulfill its sustainability-focused goals, targets and objectives within the timelines announced, or at all, could adversely affect our business or reputation, as well as expose us to potential government enforcement actions and private litigation. We cannot predict the ultimate impact of achieving Westlake's emissions reduction goal, or the various implementation aspects, on our financial condition and results of operations.

Current wording

In November 2025, Westlake announced that in 2024 it successfully met its publicly disclosed target to reduce its Scope 1 and Scope 2 CO2 equivalent emissions intensity per ton of production by 20% from a 2016 baseline. Having reached its initial 2030 emissions target, Westlake announced a new target to further reduce its Scope 1 and Scope 2 CO 2 equivalent emissions intensity per ton of production by an additional 5% by 2030, using a 2024 baseline. Developing and implementing plans for compliance with voluntary climate commitments can lead to additional capital, personnel, operations and maintenance expenditures and could significantly affect the economic position of existing facilities and proposed projects. Westlake's failure or perceived failure to pursue or fulfill its sustainability-focused goals, targets and objectives within the timelines announced, or at all, could adversely affect our business or reputation, as well as expose us to potential government enforcement actions and private litigation.

Previous wording

The Board of Governors of the Federal Reserve System increased benchmark interest rates four times in 2023 and lowered benchmark interest rates three times in 2024. However, rates remain above the ten-year average and may rise in future periods. Should interest rates increase significantly, the amount of cash required to service our debt would increase. As a result, significant increases in interest rates could have a material impact on our financial position, results of operations and cash flows.

Previous wording

If at any time our general partner and its affiliates own more than 80% of the common units, our general partner will have the right, which it may assign to any of its affiliates or to us, but not the obligation, to acquire all, but not less than all, of the common units held by unaffiliated persons at a price equal to the greater of (1) the average of the daily closing price of the common units over the 20 trading days preceding the date three days before notice of exercise of the call right is first mailed and (2) the highest per-unit price paid by our general partner or any of its affiliates for common units during the 90-day period preceding the date such notice is first mailed. As a result, unitholders may be required to sell their common units at an undesirable time or price and may not receive any return or a negative return on their investment. Unitholders may also incur a tax liability upon a sale of their units. Our general partner is not obligated to obtain a fairness opinion regarding the value of the common units to be repurchased by it upon exercise of the limited call right. There is no restriction in our partnership agreement that prevents our general partner from causing us to issue additional common units and then exercising its call right. If our general partner exercised its limited call right, the effect would be to take us private and, if the units were subsequently deregistered, we would no longer be subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act.

Members of the investment community are increasing their focus on sustainability practices and disclosures by public companies, including practices and disclosures related to climate change and sustainability, D&I initiatives and heightened governance standards. On March 6, 2024, the SEC adopted a new set of rules that require a wide range of climate-related disclosures, including material climate-related risks. Multiple lawsuits have been filed challenging the SEC's new climate rules, and on April 4, 2024, the SEC issued an order staying the final rules until judicial review is complete. In September 2023, California passed climate-related disclosure mandates that are broader than the SEC's rules. As a result, we may continue to face increasing pressure regarding our sustainability disclosures and practices. Additionally, members of the investment community may screen companies such as ours for sustainability disclosures and performance before investing in our common units. Over the past few years, there has also been an acceleration in investor demand for sustainability investing opportunities, and many large institutional investors have committed to increasing the percentage of their portfolios that are allocated towards sustainability investments. With respect to any of these investors, our sustainability disclosures and efforts may not satisfy the investor requirements or their requirements may not be made known to us. If we or our securities are unable to meet the sustainability standards or investment criteria set by these investors and funds, we may lose investors or investors may allocate a portion of their capital away from us, our cost of capital may increase, and our common unit price may be negatively impacted.

Previous wording

The present U.S. federal income tax treatment of publicly-traded partnerships, including us, or an investment in our common units, may be modified by administrative, legislative or judicial changes or differing interpretations at any time. Members of Congress and the President have frequently proposed and considered substantive changes to the existing U.S. federal income tax laws that would affect publicly-traded partnerships, including proposals that would eliminate our ability to qualify for partnership tax treatment. Recent proposals have provided for the expansion of the qualifying income exception for publicly traded partnerships in certain circumstances and other proposals have provided for the total elimination of the qualifying income exception upon which we rely for our partnership tax treatment. Further, while unitholders of publicly traded partnerships are, subject to certain limitations, entitled to a deduction equal to 20% of their allocable share of a publicly traded partnership's "qualified business income," this deduction is scheduled to expire with respect to taxable years beginning after December 31, 2025.

Moreover, the transferee of an interest in a partnership that is engaged in a U.S. trade or business is generally required to withhold 10% of the "amount realized" by the transferor unless the transferor certifies that it is not a foreign person. While the determination of a partner's "amount realized" generally includes any decrease of a partner's share of the partnership's liabilities, the Treasury Regulations provide that the "amount realized" on a transfer of an interest in a publicly-traded partnership, such as our common units, will generally be the amount of gross proceeds paid to the broker effecting the applicable transfer on behalf of the transferor, and thus will be determined without regard to any decrease in that partner's share of a publicly-traded partnership's liabilities. For a transfer of interests in a publicly traded partnership that is effected through a broker on or after January 1, 2023, the obligation to withhold is imposed on the transferor's broker. Current and prospective non-U.S. unitholders should consult their tax advisors regarding the impact of these rules on an investment in our common units.

Current report — wording carried from elsewhere

Legislation to regulate GHG emissions has periodically been introduced in the United States Congress, and such legislation may be proposed or adopted in the future. There has been a wide-ranging policy debate regarding the impact of these gases and possible means for their regulation. Some of the proposals would require industries to meet stringent new standards that would require substantial reductions in carbon emissions. The adoption and implementation of any international, federal or state legislation or regulations that restrict emissions of GHGs could result in increased compliance costs or additional operating restrictions. The EPA has adopted rules requiring the reporting of GHG emissions from specified large GHG emission sources on an annual basis including our facilities in Lake Charles and Calvert City. Various jurisdictions have considered or adopted laws and regulations on GHG emissions, with the general aim of reducing such emissions. The EPA currently requires certain industrial facilities to report their GHG emissions and to obtain permits with stringent control requirements before constructing or modifying new facilities with significant criteria pollutant and GHG emissions. On July 29, 2025, EPA released a pre-publication proposed rule which would rescind EPA's 2009 final rule under the Clean Air Act finding that GHGs endanger the public health and welfare of current and future generations ("Endangerment Finding") and that emissions of GHGs from new motor vehicles contribute to GHG pollution that threatens the public health and welfare. On September 16, 2025, the EPA announced a proposal to end the Greenhouse Gas Reporting Program ("GHGRP") for all sectors except petroleum and natural gas systems (excluding reporting for natural gas distribution, which would also be eliminated under the proposal). As our chemical processing results in GHG emissions, these and other GHG laws and regulations could affect our costs of doing business.
