NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—Continued

(Unaudited)

(in thousands of dollars, except unit amounts and per unit data)

1. Description of Business and Basis of Presentation

Description of Business

Westlake Chemical Partners LP (the "Partnership") is a Delaware limited partnership formed in March 2014 to operate, acquire and develop ethylene production facilities and related assets. On August 4, 2014, the Partnership completed its initial public offering (the "IPO") of 12,937,500 common units representing limited partner interests.

In connection with the IPO, the Partnership acquired a 10.6% limited partner interest in Westlake Chemical OpCo LP ("OpCo") and a 100% interest in Westlake Chemical OpCo GP LLC ("OpCo GP"), which is the general partner of OpCo. OpCo owns three ethylene production facilities and one common carrier ethylene pipeline (collectively, the "Contributed Assets"). Since the IPO, the Partnership has periodically purchased additional limited partner interest in OpCo. Most recently, on March 29, 2019, the Partnership purchased an additional 4.5% newly-issued limited partner interest in OpCo for approximately $201,445, resulting in an aggregate 22.8% limited partner interest in OpCo, effective January 1, 2019. The remaining 77.2% limited partner interest in OpCo is owned by Westlake ~~Chemical~~ Corporation.

Basis of Presentation

The accompanying unaudited consolidated interim financial statements were prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the "SEC") for interim periods. Accordingly, certain information and footnotes required for complete financial statements under generally accepted accounting principles in the United States ("U.S. GAAP") have not been included. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto of the Partnership included in the annual report on Form 10-K for the fiscal year ended December 31, ~~2020~~2021 (the ~~"2020~~"2021 Form 10-K"), filed with the SEC on March 2, ~~2021.~~2022. These financial statements have been prepared in conformity with the accounting principles and practices as disclosed in the notes to the consolidated financial statements of the Partnership for the fiscal year ended December 31, ~~2020.~~2021.

References to "Westlake" refer collectively to Westlake Corporation (formerly known as Westlake Chemical ~~Corporation~~Corporation) and its subsidiaries, other than the Partnership, OpCo and OpCo GP.

The Partnership holds a 22.8% limited partner interest and the entire non-economic general partner interest in OpCo. The remaining 77.2% limited partner interest in OpCo is owned directly by Westlake, which has no rights to direct the activities that most significantly impact the economic performance of OpCo. As a result of the fact that substantially all of OpCo's activities are conducted on behalf of Westlake, and the fact that OpCo exhibits disproportionality of voting rights to economic interest, OpCo was deemed to be a variable interest entity. The Partnership, through its ownership of OpCo's general partner, has the power to direct the activities that most significantly impact the economic performance of OpCo, and it also has the obligation or right to absorb losses or receive benefits from OpCo that could potentially be significant to OpCo. As such, the Partnership was determined to be OpCo's primary beneficiary and therefore consolidates OpCo's results of operations and financial position. Westlake's retained interest of 77.2% is recorded as noncontrolling interest in the Partnership's consolidated financial statements.

In the opinion of the Partnership's management, the accompanying unaudited consolidated interim financial statements reflect all adjustments (consisting only of normal recurring adjustments) that are necessary for a fair statement of the Partnership's financial position as of March 31, ~~2021,~~2022, its results of operations for the three months ended March 31, ~~2021~~2022 and ~~2020~~2021 and the changes in its cash position for the three months ended March 31, ~~2021~~2022 and ~~2020.~~2021.

Results of operations and changes in cash position for the interim periods presented are not necessarily indicative of the results that will be realized for the fiscal year ending December 31, ~~2021~~2022 or any other interim period. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. Actual results could differ materially from those estimates.

~~(in thousands of dollars, except unit amounts and per unit data)~~

~~The COVID pandemic resulted in widespread adverse impacts on the global economy in 2020.~~ The Partnership has not experienced significant disruptions to its business operations in 2020 or during the three months ended March 31, 2021 and does not expect significant disruptions to its business operations resulting from COVID-19. However, the impact that COVID-19 will have on the Partnership's financial condition, results of operations and cash flows cannot be estimated with certainty at this time as it will depend on future developments, including, among others, the timing and logistics with respect to the distribution of vaccines (in the United States, Europe and globally) and the efficacy of the available vaccines (including with respect to the more recent variants of COVID-19) and other treatments, the ultimate duration of the pandemic, geographic spread and severity of the virus, the consequences of governmental and other measures designed to prevent the spread of the virus, the impact on the operation of OpCo's facilities, Westlake, customers, suppliers and other third parties and the timing and extent to which normal economic and operating conditions resume.

~~Recent Accounting Pronouncements~~

~~Reference Rate Reform (ASU No. 2020-04)~~

In March 2020, the FASB issued an accounting standards update to provide optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update are effective for all entities as of March 12, 2020 through December 31, 2022. The Partnership is in the process of evaluating the impact that the new accounting guidance will have on the Partnership's consolidated financial position, results of operations and cash flows.

6. Distributions and Net Income Per Limited Partner Unit

On May ~~3, 2021,~~2, 2022, the board of directors of Westlake Chemical Partners GP LLC ("Westlake GP"), the Partnership's general partner, declared a quarterly cash distribution for the three months ended March 31, ~~2021~~2022 of $0.4714 per unit. This distribution is payable on May ~~27, 2021~~26, 2022 to unitholders of record as of May ~~13, 2021.~~12, 2022.

Distributions are declared subsequent to quarter end; therefore, the table below represents total cash distributions declared from earnings of the related periods pertaining to such distributions.


		Three Months Ended March 31,				Three Months Ended March 31,

Distribution in excess of net income							Distribution in excess of net income	$	(406)	$	(1,447)

Net income per unit applicable to common limited partner units is computed by dividing the respective limited partners' interest in net income by the weighted-average number of common units outstanding for the period. Because the Partnership has more than one class of participating securities, it uses the two-class method when calculating the net income per unit applicable to limited partners. The classes of participating securities include common units and incentive distribution rights. Net income attributable to the Partnership is allocated to the unitholders in accordance with their respective ownership percentages in preparation of the consolidated statements of changes in equity. However, when distributions related to the incentive distribution rights are made, net income equal to the amount of those distributions is first allocated to the general partner before the remaining net income is allocated to the unitholders based on their respective ownership percentages. Basic and diluted net income per unit is the same because the Partnership does not have any potentially dilutive units outstanding for the periods presented.

The amended Partnership Agreement provides that the Partnership will distribute cash each quarter to all the unitholders, pro rata, until each unit has received a distribution of $1.2938. If cash distributions to the Partnership's unitholders exceed $1.2938 per common unit in any quarter, the Partnership's unitholders and Westlake, as the holder of the Partnership's incentive distribution rights, will receive distributions according to the following percentage allocations:


	Marginal Percentage Interest in Distributions
Total Quarterly Distribution Per Unit	Unitholders		IDR Holders
Above $1.2938 up to $1.4063	85.0	%	15.0	%
Above $1.4063 up to $1.6875	75.0	%	25.0	%
Above $1.6875	50.0	%	50.0	%

The Partnership's distribution for the three months ended March 31, ~~2021~~2022 did not exceed the $1.2938 per unit threshold, and, as a result, no distribution was made with respect to the Partnership's incentive distribution rights to Westlake, as the holder of the Partnership's incentive distribution rights.

Distribution Per Common Unit

Distributions per common unit for the three months ended March 31, ~~2021~~2022 and ~~2020~~2021 were as follows:

During February and March 2021, due to the severe winter storm, OpCo's ethylene production facilities in the region experienced disruptions to their operations, resulting in lost production and additional maintenance and other costs. OpCo declared force majeure under the Ethylene Supply Agreement. As a result of the force majeure, the Partnership recognized a buyer deficiency fee of $5,500 in the three months ended March 31, 2021, as a component of net sales, representing fixed margin and unavoided operating and maintenance capital expenditures and maintenance expenses during the force majeure events. The buyer deficiency is an estimate based on OpCo's anticipated 2021 ethylene production. Additionally, under the Ethylene Sales Agreement, if production costs billed to Westlake on an annual basis are less than 95% of the actual production costs incurred by OpCo during the period, OpCo is entitled to recover the shortfall in the subsequent year. During the three months ended March 31, 2021, based on the additional costs incurred during the force majeure events, the Partnership recognized a shortfall of $4,178 as a component of net sales.

During 2020, the Lake Charles Petro 1 and Petro 2 facilities were impacted by Hurricanes Laura and Delta, which resulted in force majeure events under the Ethylene Sales Agreement. As a result of the force majeure events, the Partnership recognized a buyer deficiency fee of $69,555 as a component of net sales in 2020. Payment for the buyer deficiency fee was received by the Partnership in January 2021.

10. Fair Value Measurements

The Partnership reports certain assets and liabilities at fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). Under the accounting guidance for fair value measurements, inputs used to measure fair value are classified in one of three levels:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

~~Table of Contents~~

~~WESTLAKE CHEMICAL PARTNERS LP~~

~~NOTES TO CONSOLIDATED FINANCIAL STATEMENTS~~—~~Continued~~

~~(Unaudited)~~

~~(in thousands of dollars, except unit amounts and per unit data)~~

The Partnership has financial assets and liabilities subject to fair value measures. These financial assets and liabilities include cash and cash equivalents, accounts receivable, net, accounts payable and ~~long-term~~ debt payable to Westlake, all of which are recorded at carrying value. The amounts reported in the consolidated balance sheets for accounts receivable, net and accounts payable approximate their fair value due to the short maturities of these instruments. The carrying and fair values of the Partnership's ~~long-term~~ debt at March 31, ~~2021~~2022 and December 31, ~~2020~~2021 are summarized in the table below. The Partnership's ~~long-term~~ debt includes the OpCo Revolver and the MLP Revolver at March 31, ~~2021.~~2022. The fair value of debt is determined based on the present value of expected future cash flows using a discounted cash flow methodology. Because the Partnership's valuation methodology used for ~~long-term~~ debt requires the use of significant unobservable inputs, the inputs used to measure the fair value of the Partnership's ~~long-term~~ debt are classified as Level 3 within the fair value hierarchy. Inputs used to estimate the fair values of the Partnership's ~~long-term~~ debt include the selection of an appropriate discount rate.

12. Commitments and Contingencies

The Partnership is subject to environmental laws and regulations that can impose civil and criminal sanctions and that may require the Partnership to mitigate the effects of contamination caused by the release or disposal of hazardous substances into the environment. These laws include the federal Clean Air Act, the federal Water Pollution Control Act, the Resource Conservation and Recovery Act ("RCRA"), the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA"), the Toxic Substances Control Act and various other federal, state and local laws and regulations. Under CERCLA, an owner or operator of property may be held strictly liable for remediating contamination without regard to whether that person caused the contamination, and without regard to whether the practices that resulted in the contamination were legal at the time they occurred. Because the Partnership's production sites have a history of industrial use, it is impossible to predict precisely what effect these legal requirements will have on the Partnership. Westlake will indemnify the Partnership for liabilities that occurred or existed prior to August 4, 2014.

On September 27, 2021, shortly after the turnaround on Petro 2 commenced, there was a flash fire at the quench tower of the Petro 2 facility. Several contractors working on the quench tower were injured. There are lawsuits pending in connection with the flash fire. We expect insurance to cover most of the costs associated with these lawsuits.

The Partnership is also involved in ~~various~~other legal proceedings incidental to the conduct of its business. The Partnership does not believe that any of these legal proceedings will have a material adverse effect on its financial condition, results of operations or cash flows.

The following discussion contains forward-looking statements. Please read "Forward-Looking Statements" for a discussion of limitations inherent in such statements.

Partnership Overview

We are a Delaware limited partnership formed by Westlake to operate, acquire and develop ethylene production facilities and related assets. On August 4, 2014, we closed our initial public offering (the "IPO") of 12,937,500 common units. In connection with the IPO, we acquired a 10.6% interest in OpCo and a 100% interest in OpCo GP, which is the general partner of OpCo. On April 29, 2015, we purchased an additional 2.7% newly-issued limited partner interest in OpCo, resulting in an aggregate 13.3% limited partner interest in OpCo, effective April 1, 2015. The 12,686,115 subordinated units of the Partnership, all of which were previously owned by Westlake, were converted into common units of the Partnership on August 30, 2017. On September 29, 2017, we completed a secondary public offering of 5,175,000 common units and purchased an additional 5.0% newly-issued limited partner interest in OpCo, resulting in an aggregate 18.3% limited partner interest in OpCo, effective July 1, 2017. On March 29, 2019, we completed a private placement of 2,940,818 common units and used the net proceeds to purchase an additional 4.5% interest in OpCo, effective January 1, 2019, resulting in us owning an aggregate 22.8% limited partner interest in OpCo.

~~Our~~Currently, our sole revenue generating asset is our 22.8% limited partner interest in OpCo, a limited partnership formed by Westlake and us in anticipation of the IPO to own and operate an ethylene production business. We control OpCo through our ownership of its general partner. Westlake retains the remaining 77.2% limited partner interest in OpCo as well as a significant interest in us through its ownership of our general partner, 40.1% of our limited partner units (consisting of 14,122,230 common units) and our incentive distribution rights. OpCo's assets include (1) two ethylene production facilities ("Petro 1" and "Petro 2" and, collectively, "Lake Charles Olefins") at Westlake's Lake Charles, Louisiana site; (2) one ethylene production facility ("Calvert City Olefins") at Westlake's Calvert City, Kentucky site; and (3) a 200-mile common carrier ethylene pipeline (the "Longview Pipeline") that runs from Mont Belvieu, Texas to Westlake's Longview, Texas facility.

How We Generate Revenue

We generate revenue primarily by selling ethylene and the resulting co-products we produce. OpCo and Westlake have entered into an ethylene sales agreement (the "Ethylene Sales Agreement") pursuant to which we generate a substantial majority of our revenue. The Ethylene Sales Agreement is a long-term, fee-based agreement with a minimum purchase commitment and includes variable pricing based on OpCo's actual feedstock and natural gas costs and estimated other costs of producing ethylene (including OpCo's estimated operating costs and a five-year average of OpCo's expected future maintenance capital expenditures and other turnaround expenditures based on OpCo's planned ethylene production capacity for the year), plus a fixed margin per pound of $0.10 less revenue from co-products sales. Pursuant to the Ethylene Sales Agreement, Westlake's obligation to pay for the annual minimum commitment (95% of OpCo's budgeted ethylene production), which is measured on an annual basis, is not reduced for ~~the first 45 days of~~ a force majeure event ~~but is reduced for the portion of a force majeure event extending beyond the 45th day.~~lasting fewer than 45 consecutive days. In the event of a force majeure event, we recognize buyer deficiency fees representing fixed margin and unavoided operating and maintenance capital expenditures and maintenance expenses ~~associated with ethylene that OpCo would have produced and is not expected to be produced based on anticipated production.~~per pound of volume committed by Westlake during the force majeure. Payment for the buyer deficiency fee is scheduled to be received by the Partnership after the conclusion of the year.

Westlake has an option to take 95% of volumes in excess of the minimum commitment on an annual basis under the Ethylene Sales Agreement if we produce more than our planned production. Under the Ethylene Sales Agreement, the price for the sale of such excess ethylene to Westlake is based on a formula similar to that used for the minimum purchase commitment, with the exception of certain fixed costs. In addition, under the Ethylene Sales Agreement, if production costs billed to Westlake on an annual basis are less than 95% of the actual production costs incurred by OpCo during the contract year, OpCo is entitled to recover the shortfall in such production costs (proportionate to the volume sold to Westlake) in the subsequent year ("Shortfall"). The Shortfall is generally recognized during the period in which the related operating, maintenance or turnaround activities occur.

Operating Expenses, Maintenance Capital Expenditures and Turnaround Costs

Our management seeks to maximize the profitability of our operations by effectively managing operating expenses, maintenance capital expenditures and turnaround costs. Our operating expenses are comprised primarily of feedstock costs and natural gas, labor expenses (including contractor services), utility costs (other than natural gas) and turnaround and maintenance expenses. With the exception of feedstock ~~including~~(including natural ~~gas,~~gas) and utilities-related expenses, operating expenses generally remain relatively stable across broad ranges of production volumes but can fluctuate from period to period depending on the circumstances, particularly maintenance and turnaround activities. Our maintenance capital expenditures and turnaround costs are comprised primarily of maintenance of our ethylene production facilities and the amortization of capitalized turnaround costs. These capital expenditures relate to the maintenance and integrity of our facilities. We capitalize the costs of major maintenance activities, or turnarounds, and amortize the costs over the period until the next planned turnaround of the affected facility.

Operating expenses, maintenance capital expenditures and turnaround costs are built into the price per pound of ethylene charged to Westlake under the Ethylene Sales Agreement. Because the expenses other than feedstock costs and natural gas are based on forecasted amounts and remain a fixed component of the price per pound of ethylene sold under the Ethylene Sales Agreement for any given 12-month period, our ability to manage operating expenses, maintenance expenditures and turnaround ~~cost~~costs may directly affect our profitability and cash flows. The impact on profitability is partially mitigated by the fact that we generally recognize any Shortfall as revenue in the period such costs and expenses are incurred. We seek to manage our operating and maintenance expenses on our ethylene production facilities by scheduling maintenance and turnarounds over time to avoid significant variability in our operating margins and minimize the impact on our cash flows, without compromising our commitment to safety and environmental stewardship. In addition, we reserve cash on an annual basis from what we would otherwise distribute to minimize the impact of turnaround costs in the year of incurrence. The purchase price under the Ethylene Sales Agreement is not designed to cover capital expenditures for expansions.

MLP Distributable Cash Flow and EBITDA

The body of accounting principles generally accepted in the United States is commonly referred to as "GAAP." 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 GAAP in the statement of income, 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 use the non-GAAP measures of MLP distributable cash flow and EBITDA to analyze our performance. We define distributable cash flow as net income plus depreciation, amortization and disposition of property, plant and equipment, less contributions for turnaround reserves, maintenance capital expenditures and mark-to-market adjustment on derivative contracts. We define MLP distributable cash flow as distributable cash flow less distributable cash flow attributable to Westlake'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. We use each of MLP distributable cash flow and EBITDA to analyze our performance. Fees for a buyer deficiency and Shortfall are included in net income in the periods in which they are recognized. MLP distributable cash flow 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.

MLP distributable cash flow is not a substitute for the GAAP measures of net income and net cash provided by operating activities. MLP distributable cash flow has important limitations as an analytical tool because it excludes some but not all items that affect net income and net cash provided by operating activities. EBITDA is not a substitute for the GAAP measures of net income, income from operations and net cash provided by operating activities. In addition, it should be noted that companies calculate EBITDA differently and, therefore, EBITDA as presented for us may not be comparable to EBITDA reported by other companies. EBITDA has material limitations as a performance measure because it excludes interest expense, depreciation and amortization, and income taxes. Reconciliations for each of MLP distributable cash flow and EBITDA are included in the "Results of Operations" section below.

~~Significant Developments Affecting Industry Conditions and Our Business~~

~~COVID-19, Industry Conditions and Our Business~~

~~On March 11, 2020, the World Health Organization declared the ongoing coronavirus (COVID-19) outbreak a pandemic and recommended containment and mitigation measures worldwide.~~ ~~The pandemic~~ has resulted in widespread adverse impacts on the global economy and on our employees, customers and suppliers. We have not experienced significant disruptions to our business operations and do not expect to experience ~~significant disruptions to our business operations resulting from COVID-19, primarily due to the fact that 95% of our production is sold to Westlake on a take-or-pay contract.~~

Our first priority in our response to this crisis has been the health and safety of our operators, who are seconded to us by Westlake, and those of our customers and vendors. Westlake has implemented preventative measures and developed corporate and regional response plans to minimize unnecessary risk of exposure. We and Westlake have modified certain business practices (including those related to employee travel, employee work locations and employee work practices) to conform to government restrictions and best practices encouraged by the Center for Disease Control and Prevention, the World Health Organization and other governmental and regulatory authorities. We and Westlake have implemented strategies to reduce costs, increase operational efficiencies and lower capital spending. We also deferred the planned turnaround at OpCo's Petro 2 ethylene unit and associated maintenance cost from 2020 to the second half of 2021. The turnaround is expected to last approximately 60 days.

~~February Winter Storm~~

In February 2021, large parts of the southern United States, including Louisiana and Kentucky, experienced a severe winter storm. Due to the severe winter storm, OpCo's ethylene production facilities in the region experienced disruption to their operations, resulting in lost production and additional maintenance costs. OpCo declared force majeure under the Ethylene Supply Agreement during February and March 2021. As a result of the force majeure events, we recognized a buyer deficiency fee of $5.5 million and a Shortfall of $4.2 million in the first quarter of 2021 that are scheduled to be received by the Partnership after the end of 2021. The buyer deficiency fee is associated with ethylene that OpCo would have produced and is not expected to be produced in 2021 based on anticipated production. OpCo's production facilities have since resumed production.

Summary

For the quarter ended March 31, ~~2021,~~2022, net income was $80.8 million on net sales of $362.4 million. This represents an increase in net income of $4.2 million as compared to net income of $76.6 million on net sales of $268.2 ~~million. This represents a decrease in net income of $17.2 million as compared to net income of $93.8 million on net sales of $250.5~~ million for the quarter ended March 31, ~~2020.~~2021. Net income attributable to the Partnership for the first quarter of ~~2021~~2022 was ~~$15.1~~$16.2 million as compared to ~~$17.7~~$15.1 million for the first quarter of ~~2020, a decrease~~2021, an increase of ~~$2.6~~$1.1 million. Income from operations was $83.2 million for the first quarter of 2022 as compared to $79.0 million for the first quarter of 2021. Net income, ~~and~~ net income attributable to the Partnership and operating income for the first quarter of ~~2021~~2022 as compared to the first quarter of ~~2020~~2021 were ~~lower~~higher primarily due to ~~lower~~increased ethylene sales volumes ~~to Westlake~~ and third parties and higher feedstock and conversion costs. The decreases were partially offset by higher sales prices for ethylene sold to Westlake per the terms of the Ethylene Sales Agreement and to third parties, as well as the buyer deficiency fee of $5.5 million and the Shortfall of $4.2 million recognized in the first quarter of 2021 due to the force majeure events in February and March 2021 resulting from the severe winter storm. Net sales for the first quarter of 2021 increased by $17.7 million as compared to net sales for the first quarter of 2020, mainly due to higher sales prices to Westlake per the terms of the Ethylene Sales Agreement and higher co-products sales, partially offset by a decrease in ethylene sales prices to third parties ~~as well as the buyer deficiency fee~~ and ~~the Shortfall recognized during~~higher ethane feedstock and natural gas costs. Net sales for the first quarter of ~~2021, partially offset~~2022 increased by ~~lower~~$94.2 million as compared to net sales ~~volumes to Westlake and third parties during the first quarter of 2021.

Production volumes during the first quarter of 2021 were lower due to unplanned outages related to Winter storm Uri. The average sales price in the first quarter of ~~2021~~2022 contributed to a ~~22.2%~~22.0% increase in net sales, primarily due to higher ethylene sales prices to Westlake per the terms of the Ethylene Sales Agreement and ~~to third parties.~~co-product sales prices. The ~~lower~~average sales volume ~~contributed to a 19.0% decrease in net sales~~ in the first quarter of ~~2021~~2022 contributed to a 18.1% increase in net sales, primarily due to higher production resulting in increased sales volumes to Westlake and increased co-product sales volumes as compared to the first quarter of ~~2020. The decrease in sales volumes for the first quarter of 2021 was primarily due to the force majeure events as a result of the severe winter storm that impacted OpCo's production facilities.~~2021.

Gross Profit. Gross profit ~~decreased~~increased to $91.4 million for the first quarter of 2022 from $87.7 million for the first quarter of ~~2021 from $103.5 million for the first quarter of 2020.~~2021.

The decrease in the first quarter of ~~2020. The increase in the first quarter of 2021~~2022 was mainly attributable to ~~higher~~a decrease in service costs, partially offset by an increase in provision for doubtful accounts as compared to the first quarter of ~~2020.~~2021.

Interest Expense. Interest expense ~~decreased by $1.8 million to~~of $2.2 million in the first quarter of ~~2021 from $4.0 million in~~2022 was comparable to the first quarter of ~~2020, largely due to a lower average interest rate on debt.~~

~~Other Income, net.~~ Other income, net in the first quarter of 2021 decreased by $0.6 million, primarily due to a decrease in interest income earned under the Investment Management Agreement as a result of lower average interest rates.2021.

The $44.4 million increase~~decrease in cash flows from operating activities was mainly due to ~~an increase in cash provided for working capital, partially offset by~~ a decrease in ~~income~~cash used from ~~operations~~working capital during the three months ended March 31, ~~2021~~2022 as compared to the prior-year period. Changes in components of working capital, which we define for the purposes of this cash flow discussion as accounts receivable, net—Westlake, accounts receivable, net—third parties, inventories, prepaid expenses and other current assets less accounts payable—Westlake, accounts payable—third parties and accrued liabilities, ~~provided~~used cash of ~~$51.5~~$10.7 million in the first three months of ~~2021~~2022 as compared to ~~$8.7~~$51.5 million of cash ~~used~~provided in the first three months of ~~2020,~~2021, resulting in an overall ~~favorable~~unfavorable change of ~~$60.2~~$62.2 million. The ~~favorable~~unfavorable change in working capital was mainly attributable to ~~a favorable~~an unfavorable change in Westlake, net accounts receivable due to the receipt of the buyer deficiency fee related to the force majeure events in 2020 by the Partnership in January 2021, partially offset by unfavorable changes in accounts receivable, net—third parties, accounts payable and accrued and other ~~liabilities.~~liabilities due to the timing of payment of accruals related to the Petro 2 turnaround activities in 2021, as well as Westlake and third party net accounts receivable due to higher sales prices and volumes in the three months ended March 31, 2022.

Investing Activities

Net cash used for investing activities during the first three months of ~~2021~~2022 was ~~$76.6~~$25.3 million as compared to net cash used for investing activities of ~~$11.0~~$76.6 million in the first three months of ~~2020,~~2021, mainly due to ~~increased~~decreased net cash used under the Investment Management Agreement, partially offset by increased capital expenditures in the first three months of ~~2021,~~2022, as compared to the prior-year period. Capital expenditures during the first three months of ~~2021~~2022 and ~~2020~~2021 were primarily related to projects to improve production capacity or reduce costs, maintenance and safety and environmental projects at our facilities.

Financing Activities

Net cash used for financing activities during the first three months of ~~2021~~2022 was ~~$78.7~~$77.3 million as compared to net cash used byfor financing activities of ~~$95.8~~$78.7 million in the first three months of ~~2020.~~2021. The outflows during the first three months of ~~2021~~2022 were related to the distribution of ~~$62.1~~$60.7 million to Westlake and of $16.6 million to other unitholders by the Partnership. The cash outflows during the first three months of ~~2020~~2021 were related to the distribution of ~~$79.2~~$62.1 million to Westlake and of $16.6 million to other unitholders by the Partnership.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity and Financing Arrangements

Pursuant to the terms of the ~~ATM~~Equity Distribution Agreement, entered in October 2018 and amended in February 2020, among the Partnership and various investment banks, the Partnership may offer and sell the Partnership's common units from time to time to or through the ~~Managers,~~investment banks, as the Partnership's sales agents or as principals, having an aggregate offering amount of up to $50.0 million (the "ATM Program"). The Partnership intends to use the net proceeds of sales of the common units, if any, for general partnership purposes, including the funding of potential drop-downs and other acquisitions. No common units had been issued under the ATM Program as of March 31, ~~2021.~~2022.

Based on the terms of our cash distribution policy, we expect that we will distribute to our partners most of the excess cash generated by our operations. To the extent we do not generate sufficient cash flow to fund capital expenditures, we expect to fund them primarily from external sources, including borrowing directly from Westlake, as well as future issuances of equity ~~and debt interests.~~interests or debt.

The Partnership maintains separate bank accounts, but Westlake continues to provide treasury services on our behalf under the Services and Secondment Agreement. Our sources of liquidity include cash generated from operations, the OpCo Revolver, the MLP Revolver and, if necessary and possible under then current market conditions, the issuance of additional equity interests or debt. We believe that cash generated from these sources will be sufficient to meet our short-term working capital requirements and long-term capital expenditure requirements and to make quarterly cash distributions. Westlake may also provide other direct and indirect financing to us from time to time, although it is not ~~required~~obligated to do so.

In order to fund non-annual turnaround expenditures, we cause OpCo to reserve an amount for turnaround costs during each twelve-month period designed to cover future turnaround activities. Each of OpCo's ethylene production facilities requires turnaround maintenance approximately every five years. By reserving additional cash annually, we intend to reduce the variability in OpCo's cash flow. Westlake's purchase price for ethylene purchased under the Ethylene Sales Agreement includes a component (adjusted annually) designed to cover, over the long term, substantially all of OpCo's turnaround expenditures.

Westlake's credit facility and various indentures do not prevent OpCo from making distributions to us.

Table of Contents

On May ~~3, 2021,~~2, 2022, the board of directors of Westlake Chemical Partners GP LLC, our general partner, approved a quarterly distribution of $0.4714 per unit payable on May ~~27, 2021~~26, 2022 to unitholders of record as of May ~~13, 2021,~~12, 2022, which equates to a total amount of approximately $16.6 million per quarter, or approximately $66.4 million per year in aggregate, based on the number of common units outstanding on March 31, ~~2021.~~2022. We do not have a legal or contractual obligation to pay distributions on a quarterly basis or any other basis at our minimum quarterly distribution rate or any other rate.

Capital Expenditures

Westlake has historically funded expansion capital expenditures related to Lake Charles Olefins and Calvert City Olefins. Total capital expenditures for the three months ended March 31, 2022 and 2021 were $20.3 million and ~~2020 were~~ $12.7 million, ~~and $12.0 million,~~ respectively. No such funding was required by OpCo ~~to fund capital expenditures~~ during the three months ended March 31, ~~2021~~2022 and ~~2020.~~2021. We expect that Westlake will loan additional cash to OpCo to fund its expansion capital expenditures in the future, but Westlake is under no obligation to do so.

Cash and Cash Equivalents

As of March 31, ~~2021,~~2022, our cash and cash equivalents totaled ~~$17.3~~$19.2 million. In addition, we have cash invested under the Investment Management Agreement (as described below) and a revolving credit facility with Westlake available to supplement cash if needed, as described under "Indebtedness" below.

In August 2017, the Partnership, OpCo and Westlake executed the Investment Management Agreement that authorized Westlake to invest the Partnership's and OpCo's excess cash with Westlake for a term of up to a maximum of nine months. Per the terms of the Investment Management Agreement, the Partnership earns a market return plus five basis points and Westlake provides daily availability of the invested cash to meet any liquidity needs of the Partnership or OpCo. The Partnership had ~~$187.2~~$111.2 million of cash invested under the Investment Management Agreement at March 31, ~~2021.~~2022.

Indebtedness

OpCo Revolver

In connection with the IPO, OpCo entered into a $600.0 million revolving credit facility with an affiliate of Westlake, as amended in August and December 2017 and March 2020 (the "OpCo Revolver") that may be used to fund growth projects and working capital needs. The OpCo Revolver is scheduled to mature on September 25, 2023. As of March 31, ~~2021,~~2022, outstanding borrowings under the OpCo Revolver totaled $22.6 million and bore interest at the ~~LIBOR~~London Interbank Offered Rate ("LIBOR") rate plus 2.0%, which is accrued in arrears quarterly.

MLP Revolver

In 2015, we entered into a senior, unsecured revolving credit agreement with an affiliate of Westlake (the "MLP Revolver"). The MLP Revolver has a borrowing capacity of $600.0 million and is scheduled to mature in ~~2023. On~~ March ~~29, 2019,~~2023, although we intend to extend the ~~Partnership borrowed $123.5 million under~~term prior to the ~~MLP Revolver to partially fund the purchase of an additional 4.5% interest in OpCo.~~scheduled maturity date. On March 19, 2020, the Partnership entered into an amendment to the MLP Revolver, to extend the maturity date to March 19, 2023 and add a phase-out provision for LIBOR, which is to be replaced by an alternate benchmark rate. Borrowings under the MLP Revolver bear interest at a variable rate of either (a) LIBOR plus 2.0% or, if LIBOR is no longer available, (b) Alternate Base Rate plus 1.0%. The MLP Revolver provides that we may pay all or a portion of the interest on any borrowings in kind, in which case any such amounts would be added to the principal amount of the loan. The MLP Revolver requires that we maintain a consolidated leverage ratio of either (1) during any one-year period following certain types of acquisitions (including acquisitions of additional interests in OpCo), 5.50:1.0 or less, or (2) during any other period, 4.50:1.00 or less. The MLP Revolver also contains certain other customary covenants. The repayment of borrowings under the MLP Revolver is subject to acceleration upon the occurrence of an event of default. As of March 31, ~~2021,~~2022, outstanding borrowings under the MLP Revolver totaled $377.1 million and bore interest at the LIBOR rate plus 2.0%, which is accrued in arrears quarterly. We intend to use the MLP Revolver to purchase additional limited partnership interests in OpCo in the future, in the event OpCo desires to sell such additional interests to us, for other acquisitions and for general corporate purposes.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Commodity Price Risk

A substantial portion of the Partnership's products and raw materials are commodities whose prices fluctuate as market supply and demand fundamentals change. However, our direct exposure to commodity price risk is limited to approximately 5.0% of our total ethylene production, which is the portion sold to third parties. We believe we have substantially mitigated our indirect exposure to commodity price fluctuation during the term of the Ethylene Sales Agreement through the minimum purchase commitment and the cost-plus based pricing. Additionally, we may use derivative instruments to reduce price volatility risk on feedstocks and ethylene associated with the production and sales to third parties. We did not have any open derivative position at March 31, ~~2021.~~2022.

Interest Rate Risk

We are exposed to interest rate risk with respect to our outstanding debt, all of which is variable rate debt. At March 31, ~~2021,~~2022, we had total variable rate debt of $399.7 million outstanding, all of which was owed to wholly-owned subsidiaries of Westlake, and currently accrues interest at a variable rate of LIBOR plus 200 basis points. On March 19, 2020, the Partnership entered into an amendment to the MLP Revolver to extend the maturity date of the debt to March 19, 2023 and to add a phase-out provision for LIBOR, which is to be replaced by an alternate benchmark rate. The amended credit agreement bears interest at a variable rate of either (a) LIBOR plus 2.0% or, if LIBOR is no longer available, (b) Alternate Base Rate plus 1.0%. The weighted average variable interest rate of our debt as of March 31, ~~2021~~2022 was 2.2%. We will continue to be subject to interest rate risk with respect to our variable rate debt as well as the risk of higher interest cost if and when this debt is refinanced. A hypothetical increase in our average interest rate on variable rate debt by 100 basis points would increase our annual interest expense by approximately $4.0 million, of which $3.8 million would relate to the MLP Revolver and $0.2 million would relate to the OpCo Revolver, based on the March 31, ~~2021~~2022 debt balance.

LIBOR is used as a reference rate for all of our outstanding variable rate debt as of March 31, ~~2021.~~2022. The phase-out of LIBOR ~~is set to commence~~commenced at the end of 2021 and is expected to conclude by June 30, 2023. We are currently reviewing how the LIBOR phase-out will affect us, but we do not expect the impact to be material.

Item 4. Controls and Procedures

We carried out an evaluation, under the supervision and with the participation of our management, including our President and Chief Executive Officer and our Executive Vice President and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures pursuant to Rules 13a-15 or 15d-15 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as of the end of the period covered by this report. Based upon that evaluation, our President and Chief Executive Officer and our Executive Vice President and Chief Financial Officer concluded that our disclosure controls and procedures are effective with respect to (i) the accumulation and communication to our management, including our Chief Executive Officer and our Chief Financial Officer, of information required to be disclosed by us in the reports that we submit under the Exchange Act, and (ii) the recording, processing, summarizing and reporting of such information within the time periods specified in the SEC's rules and forms.

There were no changes in our internal control over financial reporting that occurred during the three months ended March 31, ~~2021~~2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

The ~~2020~~2021 Form 10-K, filed on March 2, ~~2021,~~2022, contained a description of various legal proceedings in which we are involved, including environmental proceedings. See below and Note 12 to the unaudited consolidated financial statements within this Quarterly Report on Form 10-Q for a discussion on legal proceedings, which information is incorporated by reference herein.

Under the Omnibus Agreement, Westlake ~~Chemical~~ Corporation ("Westlake") has agreed to indemnify the Partnership for certain environmental and other liabilities relating to OpCo's processing facilities and related assets.

Potential Flare Modifications. For several years, the Environmental Protection Agency ("EPA") has been conducting an enforcement initiative against petroleum refineries and petrochemical plants with respect to emissions from flares. On April 21, 2014, Westlake received a Clean Air Act Section 114 Information Request from the EPA, which sought information regarding flares at the Calvert City and Lake Charles facilities. The EPA ~~has informed~~notified Westlake that ~~the information provided leads the EPA to believe~~it believes that some of the flares are out of compliance with applicable standards. The EPA has indicated that it is seeking a consent decree that would obligate Westlake to take corrective actions relating to the alleged noncompliance. The Partnership believes the resolution of these matters may require the payment of a monetary sanction in excess of $300,000. As discussed above, Westlake is expected to fully indemnify us for such costs.

Flash Fire at Petro 2. There are lawsuits pending in connection with the flash fire at the quench tower that occurred in September 2021 during the Petro 2 turnaround, which are described in Note 12 to the consolidated financial statements included in Item 1 of this Form 10-Q. We expect insurance to cover most of the costs associated with these lawsuits.

In addition to the matters described above, the Partnership is also involved in ~~various~~other legal proceedings incidental to the conduct of its business. The Partnership does not believe that any of these legal proceedings will have a material adverse effect on its financial condition, results of operations or cash flows.

Item 1A. Risk Factors

For a discussion of risk factors, please read Item 1A, "Risk Factors" in the ~~2020~~2021 Form 10-K. There have been no material changes from those risk factors.
