BUSINESS HIGHLIGHTS
In February 2022, the Company changed its name from Westlake Chemical Corporation to Westlake Corporation reflecting our more diversified business portfolio and is now organized under one unified brand with two financial reporting segments: Performance and Essential Materials and Housing and Infrastructure Products. Westlake reorganized its operating and reporting segments to better reflect the products produced and the breadth of industries served. The Company's two newly established reporting segments replace the former segments, Olefins and Vinyls. Performance and Essential Materials includes Westlake North American Vinyls, Westlake North American Chlor-alkali & Derivatives, Westlake European & Asian Chlorovinyls, Westlake Olefins, Westlake Polyethylene and Westlake Epoxy. Performance materials includes polyethylene, PVC and epoxy. Essential materials include caustic soda, styrene, and chlorinated derivative materials. Housing and Infrastructure Products includes Westlake Royal Building Products, Westlake Pipe & Fittings, Westlake Global Compounds and Westlake Dimex. Housing products includes housing exterior and interior products, residential pipes and fittings and residential PVC compounds. Infrastructure products includes non-residential pipes and fittings and non-residential PVC compounds. These changes have been retrospectively reflected in the periods presented.
EXECUTIVE COMMENTARY
"In 2021, we accomplished a series of meaningful milestones at Westlake including record financial results and the completion of a number of strategic acquisitions. For the fourth quarter and full year of 2021, we achieved financial records for sales, net income and EBITDA, which were attributable to strong economic conditions and our strategic market positions. We were able to deliver these results despite Winter Storm Uri, Hurricane Ida, the COVID-19 pandemic and on-going supply chain interruptions. Throughout 2021, we saw strong markets across our businesses as a result of the continuing global economic expansion. Residential construction and remodeling spending drove robust demand for PVC resin, as well as products in our Housing and Infrastructure Products segment; likewise, consumer demand for packaging products spurred demand for caustic soda and polyethylene. Our record earnings in 2021 were driven by strong demand across our product portfolio while delivering life enhancing benefits to people every day," said Albert Chao, President and Chief Executive Officer.
"Looking at the Housing and Building Products acquisitions we closed in the second half of 2021, as well as our epoxy acquisition in early 2022, we have developed a larger platform for growth which should drive value through our integrated chain and expect these businesses to meaningfully contribute to earnings in 2022," continued Mr. Chao. "We have created a framework for growth by expanding our footprint in the building product markets, enhancing our position to drive greater value with new and complementary businesses. We remain focused on advancing sustainability and reducing our carbon footprint. We will continue to deliver consistent, durable and increasingly sustainable products through our market leading brands to customers in the United States and around the world, while remaining steadfast in creating value for our shareholders."
"As we look ahead, we remain confident in the fundamentals of our business and the markets in which we participate. Market conditions continue to look favorable in 2022. As the market leader in Performance and Essential Materials including PVC, polyethylene, epoxy, chlorine and caustic soda, we are well-positioned to continue to provide value to our customers and investors. The outlook also remains favorable in our Housing and Infrastructure Products with strong market indicators in 2022. With the ground work we have laid through organic growth projects and our transformative acquisitions, including most recently our new epoxy business, combined with a continued strong market outlook for our products, we are excited about the future ahead," concluded Mr. Chao.
RESULTS
Consolidated Results
The company reported record net income, excluding a tax benefit that occurred in the fourth quarter of 2017, of $644 million on record net sales of $3,507 million for the three months ended December 31, 2021. Net income in the fourth quarter of 2020 was $113 million. The increase in net income of $531 million was driven by significantly higher sales prices and margins across most of our businesses. The continued strength of residential construction coupled with the solid repair and remodeling markets drove strong demand and pricing for PVC resin as well as demand in our Housing and Infrastructure Products business. Additionally, the Performance and Essential Materials business experienced robust strength in polyethylene for packaging and consumer markets and caustic soda benefitting from increasing industrial activity, resulting in higher prices and margins.
ii

For the full year of 2021, record net income of $2,015 million increased by $1,685 million from the full year of 2020 net income of $330 million. Income from operations of $2,800 million for the full year of 2021 increased by $2,371 million from income from operations of $429 million for the full year of 2020, which was severely impacted by the global COVID-19 pandemic. The increases in net income and income from operations were primarily due to the global economic expansion, which created strong demand across our businesses as well as significantly higher sales prices and margins through our integrated chain. The earnings associated with the Housing and Infrastructure Products acquisitions in late 2021, were partially offset by the recognition of purchase accounting adjustments and closing costs.
Record EBITDA (earnings before interest expense, income taxes, depreciation and amortization) of $1,131 million for the fourth quarter of 2021 increased by $745 million compared to fourth quarter 2020 EBITDA of $386 million. Record EBITDA of $3,693 million for the full year of 2021 was $2,447 million higher than EBITDA for the year of 2020 of $1,246 million. A reconciliation 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.
Cash and Debt
Net cash provided by operating activities was $757 million for the fourth quarter of 2021 and $2,394 million for the full year 2021. As of December 31, 2021, cash and cash equivalents were $1,908 million and long-term debt was $5,180 million. Capital expenditures were $658 million for the full year 2021.
Performance and Essential Materials Segment
Performance and Essential Materials income from operations for the fourth quarter of 2021 of $821 million increased by $678 million from fourth quarter 2020 income from operations of $143 million. This increase in income from operations versus the prior-year period was due to strong demand dynamics resulting in higher prices for products in the segment. Fourth quarter 2020 was impacted by hurricane outages in Southwest Louisiana.
For the full year of 2021, Performance Materials net sales of $5,997 million increased by $2,569 million from 2020 and Essential Materials net sales of $2,673 million increased by $636 million from 2020. Both increases were attributable to significantly higher prices and elevated volumes for PVC resin, caustic soda and polyethylene. Performance and Essential Materials income from operations of $2,549 million increased by $2,318 million from income from operations of $231 million for the full year of 2020. This increase in income from operations versus the prior-year period was primarily due to significantly higher sales and integrated margins for PVC resin, caustic soda and polyethylene. Income from operations for the full year of 2021 was additionally impacted by Winter Storm Uri and Hurricane Ida, while income from operations for the full year of 2020 was impacted by the onset of the COVID-19 pandemic and Hurricanes Laura and Delta.
Housing and Infrastructure Products Segment
For the fourth quarter of 2021, Housing and Infrastructure Products income from operations of $86 million increased by $21 million from fourth quarter 2020 income from operations of $65 million. This increase in income from operations versus the prior-year period was the result of robust housing and remodeling activity driving healthy demand and higher prices for all products in the segment.
For the full year of 2021, Housing Products net sales of $2,334 million increased by $837 million from 2020 and Infrastructure Products net sales of $774 million increased by $232 million from 2020, both increases were attributable to significantly higher prices and higher sales volumes including those of recent acquisitions driven by housing construction and remodeling activity. Housing and Infrastructure Products income from operations of $356 million increased by $100 million from income from operations of $256 million for the full year of 2020. This increase in income from operations was primarily due to significantly higher sales and margins driven by robust housing construction and remodeling activity driving increased demand. Additionally, 2021 experienced higher energy costs as well as the impacts from Winter Storm Uri and Hurricane Ida, while income from operations for 2020 was impacted by the onset of the COVID-19 pandemic and Hurricanes Laura and Delta.

Forward-Looking Statements
The statements in this release and the related teleconference relating to matters that are not historical facts, including statements regarding favorable market conditions, our outlook for our business segments, our ability to create value and grow, the contribution of recent acquisitions and demand for our products, 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: the COVID-19 pandemic and the response thereto; general economic and business conditions; the cyclical nature of the industry; availability, cost and volatility of raw materials and utilities, including natural gas and natural gas liquids from shale production; the price of crude oil; uncertainties associated with the United States and worldwide economies, including those due to global economic and financial conditions; governmental regulatory actions, including environmental regulation and changes in trade policies; political unrest; industry production capacity and operating rates; the supply/demand balance for Westlake's products; competitive products and pricing pressures; access to capital markets; technological developments; the effect and results of litigation and settlements of litigation; operating interruptions; the ability to integrate the recent acquisitions; the diversion of management time on transaction-related issues; and other risk factors. For more detailed information about the factors that could cause actual results to differ materially, please refer to Westlake's Annual Report on Form 10-K for the year ended December 31, 2020, which was filed with the SEC in February 2021 and Quarterly Report on Form 10-Q for the quarters ended March 31, 2021, June 30, 2021 and September 30, 2021 which were filed with the SEC in May 2021, August 2021 and November 2021, respectively.
Use of Non-GAAP Financial Measures
This release makes reference to certain "non-GAAP" financial measures, such as EBITDA, as defined in Regulation G of the U.S. Securities Exchange Act of 1934, as amended. 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 report our financial results in accordance with U.S. generally accepted accounting principles ("U.S. GAAP"), but believe that certain non-GAAP financial measures, such as EBITDA, provide useful supplemental information to investors regarding the underlying business trends and performance of the Company's 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. A reconciliation 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.

(8)Average USGC-CSLi index values for caustic soda over the period. As stated by IHS, "the caustic soda price listing represents the USGC-CSLi values. USGC-CSLi does not reflect contract price discounts, implementation lags, caps or other adjustments factors. Additionally, it is not intended to represent a simple arithmetic average of all market transactions occurring during the month. Rather, the USGC-CSLi is most representative of the month-to-month caustic soda price movement for contract volumes of liquid 50% caustic soda rather than the absolute value of contract prices at a particular point in time. It is intended to serve only as a benchmark."
(9)Average North American contract prices of chlorine over the period.
