Annual Report

Dear Shareholders,

Westlake celebrated our 35th anniversary in 2021 while achieving two important milestones: record financial results and 
transformational growth of our business portfolio. The momentum we carried into 2021 drove record net sales of $11.8 
billion, record net income of $2 billion ($15.58 per diluted share), and record EBITDA of $3.7 billion. These results were 
achieved in spite of the challenges we faced, including the landfall of a hurricane in Lake Charles, Louisiana; a severe 
freeze across Texas and Louisiana, where we have approximately one-third of our global production and where a large 
number of our employees reside; and the continued health and economic impacts of Covid-19. While 2021 brought many 
challenges, it also presented many opportunities. Our key markets in housing repair and remodeling, new construction, 
flexible food and consumer packaging, and industrial applications remained strong throughout the year. We greatly 
expanded our business portfolio with four transformational acquisitions totaling $3.8 billion, that propelled our market-
leading product portfolio closer to the consumer.

The acquisitions of Boral North America’s building products business, LASCO Fittings and Dimex, which closed in 
the second half of 2021, expanded our geographic reach and the breadth of our product offerings in housing and 
infrastructure products. The Boral acquisition expanded our leading branded market position in vinyl siding products 
with additions in siding, trim and molding as well as roofing, decorative stone, windows and outdoor living products. The 
acquisition of LASCO Fittings complements our Westlake Pipe and Fittings business, creating one of the nation’s largest 
manufacturers of PVC pipe and fittings. We also acquired Dimex, a manufacturer of consumer products made from 
post-industrial recycled polyethylene and PVC, such as garden edging, floor matting and dock edging sold throughout 
the nation in big-box home improvement retailers and on-line through nationally known e-commerce platforms. These 
three acquisitions helped to transform Westlake’s downstream building products business into our new Housing & 
Infrastructure Products segment. The acquisition of Hexion’s global epoxy business, which closed in the first quarter of 
2022, brings composite and coating products used in many applications including the light-weighting of automobiles and 
aircraft and in blades used in wind turbines, a key source of renewable energy. These new lines of business expand our 
existing chlorovinyls and polyethylene businesses, broadening our new Performance & Essential Materials segment.

We have a long-standing belief in delivering sustainable value to our customers, investors, employees, and the 
communities in which we operate. Westlake continues to make significant investments in new, sustainable products and 
reducing the impact on the environment. In addition to the sustainable contributions provided by Westlake Dimex and 
Westlake Epoxy, we have introduced products with lower carbon emissions as well as consuming fewer resources. These 
include the world’s first lower-carbon caustic soda and PVC, which are manufactured with renewable energy sources. 
Westlake has also introduced a new PVC-oriented pipe that uses substantially less PVC resin to manufacture pipe for use 
in municipal water delivery. This lighter-weight, yet equally strong, pipe makes installation easier and saves new material 
and transportation costs by reducing overall weight of deliveries. In early 2022, Westlake announced its 2030 target to 
reduce carbon dioxide equivalent emissions per ton of production by 20% from a 2016 baseline. We intend to achieve 
this goal by continuing to invest in both proven and emerging technologies, including energy-efficient projects, product 
and operational innovations, increasing power from less carbon-intensive power providers, adding more hydrogen as 
fuel gas and other continuous operational improvements. Westlake’s active involvement in many organizations engaged 
in sustainability, including the Alliance to End Plastic Waste, is focused on reducing waste and developing innovations to 
meet customer needs while reducing the environmental impact, creating a more sustainable future.

With the record-setting year of 2021 and the strategic growth we have achieved, coupled with the recent 
transformational acquisitions, we changed the company’s name to Westlake Corporation in February 2022 to better 
reflect the more expansive nature of our business.

As Westlake continues to grow, we remain anchored to our values and purpose: To protect the health and safety 
of our employees, deliver on our commercial commitments and deliver value to our shareholders. We are grateful 
to our stakeholders, employees and shareholders whose contributions make us a continued success. 2021 was a 
transformational year, and we believe we built significant momentum moving into 2022, integrating the new acquisitions 
into Westlake, capturing the synergies and bringing a more expansive product portfolio to serve our customers with 
sustainable products. 

Sincerely,

Albert Chao 
President and Chief Executive Officer

James Chao 
Chairman of the Board

Explanatory Note

Cautionary Statements about Forward-Looking Statements

The Private Securities Litigation Reform Act of 1995 provides safe harbor provisions for forward-looking

information. Certain of the statements contained in this Form 10-K are forward-looking statements. All
statements, other than statements of historical facts, included in this Form 10-K that address activities, events or
developments that we expect, project, believe or anticipate will or may occur in the future are forward-looking
statements. Forward-looking statements can be identified by the use of words such as “believes,” “intends,”
“may,” “should,” “could,” “anticipates,” “expected” or comparable terminology, or by discussions of strategies
or trends. Although we believe that the expectations reflected in such forward-looking statements are reasonable,
we cannot give any assurances that these expectations will prove to be correct. Forward-looking statements relate

We have based these statements on assumptions and analyses in light of our experience and perception of

historical trends, current conditions, expected future developments and other factors we believe were appropriate
in the circumstances when the statements were made. Forward-looking statements by their nature involve
substantial risks and uncertainties that could significantly impact expected results, and actual future results could
differ materially from those described in such statements. While it is not possible to identify all factors, we
continue to face many risks and uncertainties. Among the factors that could cause actual future results to differ
materially are the risks and uncertainties discussed under “Risk Factors” and those described from time to time in
our other filings with the SEC including, but not limited to, the following:

these factors, could materially affect our future results of operations and the ultimate accuracy of the forward-
looking statements. These forward-looking statements are not guarantees of our future performance, and our

ii

actual results and future developments may differ materially from those projected in the forward-looking
statements. Management cautions against putting undue reliance on forward-looking statements or projecting any
future results based on such statements or present or prior earnings levels. Every forward-looking statement
speaks only as of the date of the particular statement, and we undertake no obligation to publicly update or revise
any forward-looking statements.

Industry and Market Data

Industry and market data used throughout this Form 10-K were obtained through internal company
research, surveys and studies conducted by unrelated third parties and publicly available industry and general
publications, including information from IHS Markit (“IHS”). We have not independently verified market and
industry data from external sources. While we believe internal company estimates are reliable and market
definitions are appropriate, neither such estimates nor these definitions have been verified by any independent
sources.

Production Capacity

Unless we state otherwise, annual production capacity estimates used throughout this Form 10-K represent

rated capacity of the facilities at December 31, 2021. We calculated rated capacity by estimating the number of
days in a typical year that a production unit of a plant is expected to operate, after allowing for downtime for
regular maintenance, and multiplying that number by an amount equal to the unit’s optimal daily output based on
the design feedstock mix. Because the rated capacity of a production unit is an estimated amount, actual
production volumes may be more or less than the rated capacity.

Item 1. Business

General

PART I

We are a vertically integrated global manufacturer and marketer of performance and essential materials and
housing and infrastructure products that enhances the lives of people every day. Our products include some of the
most widely used materials in the world, which are fundamental to many diverse consumer and industrial
markets, including residential construction, flexible and rigid packaging, automotive products, healthcare
products, water treatment, coatings as well as other durable and non-durable goods. We have historically
operated in two principal operating segments, Vinyls and Olefins. As a result of recent acquisitions, in the fourth
quarter of 2021, we reorganized our business into two principal operating segments, Performance and Essential
Materials and Housing and Infrastructure Products. Performance and Essential Materials includes Westlake
North American Vinyls, Westlake North American Chlor-alkali & Derivatives, Westlake European & Asian
Chlorovinyls, Westlake Olefins and Westlake Polyethylene. Housing and Infrastructure Products includes
Westlake Royal Building Products, Westlake Pipe & Fittings, Westlake Global Compounds and Westlake
Dimex. The change has been retrospectively reflected in the periods presented in this Form 10-K. We are highly
integrated along our materials chain with significant downstream integration from ethylene and chlor-alkali
(chlorine and caustic soda) into vinyls, polyethylene and styrene monomer. We also have substantial downstream
integration from PVC into our building products, PVC pipes and fittings and PVC compounds in our Housing
and Infrastructure Products segment.

We began operations in 1986. Since 1986, we have grown rapidly into an integrated global producer of

chemicals and building products. We achieved this growth by acquiring existing plants or constructing new
plants and completing numerous capacity or production line expansions. We regularly consider acquisitions and
other internal and external growth opportunities that would be consistent with, or complementary to, our overall
business strategy.

In 2014, we formed Westlake Chemical Partners LP (“Westlake Partners”) to operate, acquire and develop

ethylene production facilities and related assets. Also in 2014, Westlake Partners completed an initial public
offering of common units (the “Westlake Partners IPO”). As of February 16, 2022, Westlake Partners’ assets
consisted of a 22.8% limited partner interest in Westlake Chemical OpCo LP (“OpCo”), as well as the general
partner interest in OpCo. Prior to the Westlake Partners IPO, OpCo’s assets were wholly-owned by us. OpCo’s
assets include two ethylene production facilities at our olefins facility in Lake Charles, one ethylene production
facility at our Calvert City site and a 200-mile common carrier ethylene pipeline that runs from Mont Belvieu,
Texas to the Longview, Texas site, which includes our Longview polyethylene production facility. We retain a
77.2% limited partner interest in OpCo, a 40.1% limited partner interest in Westlake Partners (consisting of
14,122,230 common units), a general partner interest in Westlake Partners and incentive distribution rights. The
operations of Westlake Partners are consolidated in our financial statements. We are party to certain agreements
with Westlake Partners and OpCo whereby, among other things, OpCo sells us 95% of the ethylene it produces
on a cost-plus basis that is expected to generate a fixed margin per pound of $0.10. We use this ethylene in the
production processes of our Performance and Essential Materials segment. For more information, see “—
Performance and Essential Materials Business” below.

On January 2, 2019, we completed the acquisition of NAKANTM, a global compounding solutions business.

NAKAN’s products are used in a wide-variety of applications, including in the automotive, building and
construction, and medical industries. With this acquisition, our PVC compounding business now has facilities

1

worldwide in China, France, Germany, Italy, Japan, Mexico, Spain, the United States and Vietnam, as well as a
world-class research facility in France and several application laboratories.

On November 12, 2019, we completed the acquisition of an additional 34.8% of the membership interests
in LACC, LLC (“LACC”) from Lotte Chemical USA Corporation, a subsidiary of Lotte Chemical Corporation
(“Lotte”), for approximately $817 million (the “Transaction”). Prior to the Transaction, we owned approximately
12% of the membership interests in LACC. As of December 31, 2021, we owned an aggregate 46.8%
membership interest in LACC. The LACC ethylene plant has 2.2 billion pounds per year of ethylene production
capacity and is adjacent to our chlor-alkali facility in Lake Charles. During the third quarter of 2019, the LACC
ethylene plant began commercial operations. As a result of the Transaction, we receive our proportionate share of
LACC’s ethylene production on a cash-cost basis, which is expected to benefit our integrated downstream
operations.

In January 2022, we notified Lotte of our exercise of an option to acquire an additional 3.2% membership

interest in LACC from Lotte for approximately $90 million.

On June 20, 2021, we, through one of our wholly-owned subsidiaries, entered into an Equity Purchase

Agreement (the “Boral Purchase Agreement”) by and among Boral Building Products Inc., a Michigan
corporation, Boral Stone Products LLC, a Delaware limited liability company, Boral Lifetile Inc., a California
corporation, Boral Windows LLC, a Utah limited liability company, Boral Industries Inc., a California
corporation (“Boral Industries”), and, solely for the limited purposes set forth therein, we and Boral Limited, an
Australian corporation (“Boral”). Pursuant to the terms of the Boral Purchase Agreement, we agreed to acquire
from Boral Industries all of the issued and outstanding equity interests of certain subsidiaries of Boral Industries
engaged in Boral’s North American building products businesses in roofing, siding, trim and shutters, decorative
stone and windows (the “Boral Target Companies”). On October 1, 2021, we completed the acquisition of the
Boral Target Companies (the “Boral Acquisition”). The total closing purchase consideration was $2,132 million
subject to working capital post-closing adjustments as well as a potential earn-out payment of up to $65 million if
the windows division of Boral Target Companies generates EBITDA in excess of a specified target in its fiscal
year ending June 30, 2024. The assets acquired and liabilities assumed and the results of operations of this
business are included in the Housing and Infrastructure Products segment.

On August 19, 2021, we completed the acquisition of, and acquired all of the equity interests in LASCO

Fittings, Inc. (“LASCO”), a manufacturer of injected-molded PVC fittings that serve the plumbing, pool and spa,
industrial, irrigation and retail markets in the United States from Aalberts U.S. Holding Corp. and Aalberts N.V.
(the “LASCO Acquisition”). The total closing purchase consideration was $277 million. The assets acquired and
liabilities assumed and the results of operations of LASCO are included in the Housing and Infrastructure
Products segment.

On September 10, 2021, we completed the acquisition of, and acquired all of the equity interests in, DX

Acquisition Corp. (“Dimex”), a producer of various consumer products made from post-industrial-recycled
polyvinyl chloride, polyethylene and thermoplastic elastomer materials, including, landscape edging; industrial,
home and office matting; marine dock edging; and masonry joint controls (the “Dimex Acquisition” and,
together with the Boral Acquisition and the LASCO Acquisition, the “2021 Acquisitions”). The total closing
purchase consideration was $172 million. The assets acquired and liabilities assumed and the results of
operations of Dimex are included in the Housing and Infrastructure Products segment.

On February 1, 2022, we completed the acquisition of the global epoxy business of Hexion Inc. (“Hexion

epoxy”). The total closing purchase consideration was approximately $1,200 million, subject to post-closing

2

adjustments (the “Hexion Acquisition” and, together with the 2021 Acquisitions, the “Acquisitions”). The assets
acquired and liabilities assumed and the results of operations of Hexion epoxy will be included in the
Performance and Essential Materials segment. This acquisition represents a significant strategic expansion of
Westlake’s Performance and Essential Materials businesses into additional high-growth, innovative and
sustainable-oriented applications—such as wind turbine blades and light-weight automotive structural
components. Because epoxies are produced from chlorine and caustic soda, the transaction also provides vertical
integration with Westlake’s global chlor-alkali businesses.

Performance and Essential Materials Business

Products

Principal products in our integrated Performance and Essential Materials segment include ethylene,

polyethylene, styrene, chlor-alkali (chlorine and caustic soda) and chlorinated derivative products, ethylene
dichloride (“EDC”), VCM and PVC. We manage our integrated vinyls production chain to optimize product
margins and capacity utilization.

We manufacture ethylene through three of the OpCo plants and our portion of LACC’s production capacity

located in Lake Charles and Calvert City. Chlor-alkali materials are produced at our three plants located in Lake
Charles, two plants located in Germany and one plant each located in Calvert City, Plaquemine, Geismar,
Natrium, Longview and Beauharnois. Our VCM is produced at our two plants in Lake Charles, two plants
located in Germany and one plant each at Calvert City, Plaquemine and Geismar. Our PVC is produced at our
four plants located in Germany and one plant each at Calvert City, Plaquemine, Geismar and Aberdeen.
Polyethylene and associated products are produced at our two polyethylene plants in Lake Charles and three
polyethylene plants and a specialty polyethylene wax plant at our Longview site. Our chlorinated derivative
products are produced at our plants in Lake Charles and Natrium. Styrene monomer is produced at our plant
located in our Lake Charles facility. Our Asian manufacturing facilities are located near Shanghai, in China, and
in Kaohsiung, Taiwan, through our 95%- and 60%-owned joint ventures, respectively, where we produce chlor-

Ethylene. Ethylene is the world’s most widely used petrochemical in terms of volume. It is the key building

block used to produce a large number of higher value-added chemicals including polyethylene, EDC, VCM and
styrene. OpCo has the capacity to produce approximately 3.0 billion pounds of ethylene per year at our Lake
Charles site, and we have the capability to consume all of OpCo’s production that we purchase at Lake Charles to
produce EDC, VCM, polyethylene and styrene monomer. In addition, we (through OpCo) produce ethylene
co-products including chemical grade propylene, crude butadiene, pyrolysis gasoline and hydrogen. We (through
OpCo) sell our entire output of these co-products to external customers. The ethylene from OpCo’s facility in
Calvert City and LACC is utilized to produce VCM at our facilities. We obtain the remainder of the ethylene we
need for our business from third party purchases. The use of ethane feedstock by our ethylene plants enables us
to enhance our low-cost materials chain integration.

Chlorine and Caustic Soda. We are the second-largest chlor-alkali producer in the world. We combine salt

and electricity to produce chlorine and caustic soda, commonly referred to as chlor-alkali, at our Lake Charles,
Plaquemine, Natrium, Calvert City, Geismar, Beauharnois, Longview (WA), Gendorf, Knapsack and Kaohsiung
facilities. We use our chlorine production in our VCM and chlorinated derivative products plants. We currently
have the capacity to supply all of our chlorine requirements internally. Any remaining chlorine is sold into the
merchant chlorine market. Our caustic soda is sold to external customers who use it for, among other things, the
production of pulp and paper, organic and inorganic chemicals and alumina.

VCM. VCM is used to produce PVC, solvents and PVC-related products. We use ethylene and chlorine to

produce EDC, which is used in turn, to produce VCM. We have the capacity to produce approximately
6.3 billion pounds and 1.6 billion pounds of VCM per year at our North American and European facilities,
respectively. The majority of our VCM is used internally in our PVC operations. VCM and EDC not used
internally are sold externally.

PVC. PVC, the world’s third most widely used plastic, is an attractive alternative to traditional materials

such as glass, metal, wood, concrete and other plastic materials because of its versatility, durability and cost-
competitiveness. PVC is produced from VCM, which is, in turn, made from chlorine and ethylene.

We are the second-largest PVC producer in the world. With the completion of our previously announced

expansion projects at our Geismar and Burghausen plants in 2019, we have the capacity to produce
approximately 6.8 billion pounds and 1.0 billion pounds of commodity and specialty PVC per year, respectively,
at our various facilities globally. We use some of our PVC internally in the production of our building products,
PVC pipes and fittings and PVC compounds in the Housing and Infrastructure Products segment. The remainder
of our PVC is sold to downstream fabricators and the international markets.

Polyethylene. Polyethylene, the world’s most widely consumed polymer, is used in the manufacture of a

wide variety of film, coatings and molded product applications primarily used in packaging. Polyethylene is

5

generally classified as either LDPE, LLDPE or high-density polyethylene (“HDPE”). The density correlates to
the relative stiffness of the end-use products. The difference between LDPE and LLDPE is molecular, and
products produced from LLDPE, in general, have higher strength properties than products produced from LDPE.
LDPE exhibits better clarity and other physical properties and is used in end products such as bread bags, food
wraps, milk carton coatings and food packaging. LLDPE is used for higher film strength applications such as
stretch film and heavy-duty sacks. HDPE is used to manufacture products such as grocery, merchandise and trash
bags, rigid plastic containers, plastic closures and pipe.

We are a leading producer of LDPE by capacity in North America and predominantly use the autoclave
technology (versus tubular technology), which is capable of producing higher-margin specialty polyethylene
products. In 2021, our annual capacity of approximately 1.5 billion pounds of LDPE was available in numerous
formulations to meet the needs of our diverse customer base. We also have the capacity to produce
approximately 1.1 billion pounds of LLDPE per year in various formulations. We produce LDPE and LLDPE at
both the Lake Charles and Longview (TX) facilities. Our Lake Charles and Longview facilities also have the
capability to produce HDPE. We sell polyethylene to external customers as a final product in pellet form.

Chlorinated Derivative Materials. Our chlorinated derivative products include ethyl chloride,
perchloroethylene, trichloroethylene, tri-ethane® solvents, VersaTRANS® solvents, calcium hypochlorite,
hydrochloric acid (“HCL”) and pelletized caustic soda (“PELS”). We have the capacity to produce approximately
2.3 billion pounds of chlorinated derivative products per year, primarily at our Lake Charles, Natrium,
Beauharnois and Longview (WA) facilities. The majority of our chlorinated derivative products are sold to
external customers who use these products for, among other things, refrigerants, water treatment applications,
chemicals and pharmaceutical production, food processing, steel pickling, solvent and cleaning chemicals and
natural gas and oil production.

Styrene. Styrene is used to produce derivatives such as polystyrene, acrylonitrile butadiene styrene,

unsaturated polyester and synthetic rubber. These derivatives are used in a number of applications including
consumer disposables, food packaging, housewares, paints and coatings, building materials, tires and toys. We
produce styrene at our Lake Charles plant, where we have the capacity to produce approximately 570 million
pounds of styrene per year, all of which is sold to external customers.

Electricity. Our Lake Charles, Plaquemine and Natrium cogeneration assets have the capacity to generate

electricity of approximately 420, 240 and 100 megawatts, respectively, per year. Our North American joint
ventures include a 50% interest in RS Cogen L.L.C. (“RS Cogen”) that generates electricity, of which our share
is approximately 212 megawatts.

Feedstocks

We are highly integrated along our materials production chain. We (through OpCo) produce most of the

ethylene required to produce our polyethylene and styrene. Ethylene can be produced from either petroleum
liquid feedstocks, such as naphtha, condensates and gas oils, or from natural gas liquid feedstocks, such as
ethane, propane and butane. Both of OpCo’s Lake Charles ethylene plants use ethane as the primary feedstock.
Pursuant to a feedstock supply agreement between us and OpCo, OpCo receives ethane feedstock at our Lake
Charles site through several pipelines from a variety of suppliers in Texas and Louisiana. We own a 50% interest
in a 104-mile natural gas liquids pipeline from Mont Belvieu to our Lake Charles site. OpCo owns a 200-mile
ethylene pipeline that runs from Mont Belvieu to our Longview (TX) site. Additionally, through OpCo, we
produce most of the ethylene required at our Calvert City facility utilizing ethane feedstock. The LACC ethylene

6

facility is located adjacent to our chlor-alkali facility in Lake Charles and has an ethylene production capacity of
2.2 billion pounds per year. During the third quarter of 2019, the LACC ethylene plant began its commercial
operations. At December 31, 2021, we, through one of our subsidiaries, owned 46.8% of the membership
interests in LACC. We receive our proportionate share in ethylene production on a cash-cost basis and primarily
use it to produce VCM. In addition to ethylene supplied by OpCo and LACC, we also acquire ethylene from third
parties in order to supply a portion of our ethylene requirements. In Germany, we have access to, and partially
own, an ethylene pipeline.

We acquire butene and hexene to manufacture polyethylene and benzene to manufacture styrene. We
receive butene and hexene at the Lake Charles site and hexene at the Longview (TX) site via rail car from several
suppliers. We receive benzene via barges, ships and pipeline pursuant to short-term arrangements. We purchase
butene and hexene pursuant to multi-year contracts.

The salt requirements for several of our larger chlor-alkali plants are supplied internally from salt domes

we either own or lease and the salt is transported by pipelines we own. We purchase the salt required for our
other chlor-alkali plants pursuant to long-term contracts. Electricity and steam for one of our Lake Charles
facilities are produced by both on-site cogeneration units and through a toll arrangement with RS Cogen, a joint
venture in which we own a 50% interest. RS Cogen operates a process steam, natural gas-fired cogeneration
facility adjacent to the site. Electricity and steam for the Plaquemine facility are supplied internally by our on-site
cogeneration unit. A portion of our Natrium facility’s electricity requirements is produced by our on-site
generation unit, and the remainder is purchased. We purchase electricity for our remaining facilities under long-
term contracts. We purchase VCM for our Asian PVC plant on a contract and spot basis.

Sustainability

As a leading global producer of plastics, we understand the importance of reducing the environmental
impact of our feedstocks, production and usage, and developing innovations, together with our customers, to
meet their objectives while also reducing their environmental impact. To further these objectives, we have
launched environmentally friendly product innovations. In 2021, we introduced our GreenVinTM Caustic Soda
and GreenVinTM PVC products in Germany. Due to the extensive global use of PVC and caustic soda, these
developments present an opportunity for Westlake customers to enhance the sustainable qualities of their
products.

Caustic Soda is an essential ingredient for the production of many materials, ranging from paper,

detergents, construction materials, food packaging, pharmaceuticals and water treatments products. The plants of
our German subsidiary Vinnolit, have been producing caustic soda in chlor-alkali electrolysis exclusively with
the energy-saving and environmentally friendly membrane process since 2009. Since the central process step is
electrified, power from renewable sources can be used to save CO2 emissions by displacing fossil fuels. By using
such renewable power sources, the CO2 footprint of GreenVinTM Caustic Soda is reduced by approximately 30%
compared to conventional Vinnolit caustic soda.

PVC is an essential ingredient in making some of the world’s most prevalent items, including residential
siding, pipe and fittings for various water, sewer and industrial applications, PVC profiles for windows, doors,
fence, resin paste and artificial leather among others and decking along with films for various inflatables,
wallcovering, tapes and roofing applications. The CO2 footprint of Vinnolit’s new lower-carbon PVC, which was
introduced to the market under the brand name GreenVinTM and is produced with power from renewable sources,
is reduced by approximately 25% compared to conventional Vinnolit PVC.

Marketing, Sales and Distribution

We have a dedicated sales force for our business, organized by product line and region that sells our
products directly to our customers. In addition, we rely on distributors to market products to smaller customers.
Our polyethylene customers are some of the nation’s largest producers of film and flexible packaging. We and
OpCo sell ethylene and ethylene co-products to external customers. OpCo’s primary ethylene co-products are
chemical grade propylene, crude butadiene, pyrolysis gasoline and hydrogen. We have storage agreements and
exchange agreements that provide us and OpCo with access to customers who are not directly connected to the
pipeline system that we own. OpCo ships crude butadiene and pyrolysis gasoline by rail or truck. Additionally,
we transport our polyethylene and styrene by rail or truck. Further, styrene can be transported by barge or ship.

We use some of our PVC internally in the production of our building products, pipes and fittings and PVC

compounds in the Housing and Infrastructure Products segment. The remainder of our PVC is sold to
downstream fabricators and the international markets. We have the capacity to use a majority of our chlorine
internally to produce VCM and EDC, most of which, in turn, is used to produce PVC. We also use our chlorine
internally to produce chlorinated derivative products. We sell the remainder of our chlorine and substantially all
of our caustic soda production to external customers. The majority of our products are shipped from production
facilities directly to the customer via pipeline, truck, rail, barge and/or ship. The remaining products are shipped
from production facilities to third party chemical terminals and warehouses until being sold to customers.

No single customer accounted for 10% or more of net sales for the Performance and Essential Materials

segment in 2021.

No single customer accounted for 10% or more of net sales for the Housing and Infrastructure Products

segment in 2021.

Competition

The markets in which our housing and infrastructure businesses operate are highly competitive.

Competition in the housing and infrastructure products market is based on product quality, product innovation,
customer service, product consistency, on-time delivery and price. We compete in the housing and infrastructure
products market with other producers and fabricators including Associated Materials LLC., CertainTeed
Corporation, Cornerstone Building Brands, Inc., Diamond Plastics Corporation, IPEX Inc., JM Eagle Inc., Trex
Company, Inc. and The Azek Company and with producers of PVC compounds including GEON Performance
Solutions and Teknor Apex Company, Inc.

Seasonality

Though we generally experience demand for our products throughout the year, our sales, particularly of
housing products have historically experienced some seasonality. We have typically experienced moderately
higher levels of sales of our residential products in the first half of the year due to inventory restocking and
improved weather for construction. Our sales are affected by the individual decisions of distributors and dealers
on the levels of inventory they carry, their views on product demand, their financial condition and the manner in
which they choose to manage inventory risk. Our sales are also generally impacted by the number of days in a
quarter or a year that contractors and other professionals are able to install our products. This can vary
dramatically based on, among other things, weather events such as rain, snow and extreme temperatures. We
have generally experienced lower levels of sales of our housing products in the fourth quarter due to adverse
weather conditions in certain markets, which typically reduces the construction and renovation activity during the
winter season.

Environmental

As is common in our industry, we are subject to environmental laws and regulations related to the use,

storage, handling, generation, transportation, emission, discharge, disposal and remediation of, and exposure to,
hazardous and non-hazardous substances and wastes in all of the countries in which we do business. National,
state or provincial and local standards regulating air, water and land quality affect substantially all of our
manufacturing locations around the world. Compliance with such laws and regulations has required and will
continue to require capital expenditures and increase operating costs.

It is our policy to comply with all environmental, health and safety requirements and to provide safe and

environmentally sound workplaces for our employees. In some cases, compliance can be achieved only by
incurring capital expenditures. In 2021, we made capital expenditures of $33 million related to environmental
compliance. We estimate that we will make capital expenditures of approximately $56 million in 2022 and
$83 million in 2023, respectively, related to environmental compliance. The expected 2022 and 2023 capital

11

expenditures are relatively higher than the amounts we have spent related to environmental compliance in recent
years in large part due to capital expenditures related to previously existing and new Environmental Protection
Agency (the “EPA”) regulations and corrective actions required by the EPA to resolve the flare enforcement
matter discussed below. The remainder of the 2022 and 2023 estimated expenditures are related to equipment
replacement and upgrades. We anticipate that stringent environmental regulations will continue to be imposed on
us and the industry in general. Although we cannot predict with certainty future expenditures, management
believes that our current spending trends will continue.

From time to time, we receive notices or inquiries from government entities regarding alleged violations of

environmental laws and regulations pertaining to, among other things, the disposal, emission and storage of
chemical substances, including hazardous wastes. Pursuant to Item 103 of the SEC’s Regulation S-K, the
following environmental matters involve a governmental authority as a party to the proceedings and potential
monetary sanctions that we believe could exceed $1 million (which is less than one percent of our current assets
on a consolidated basis as of December 31, 2021):

(cid:129)

For several years, the EPA has been conducting an enforcement initiative against petroleum
refineries and petrochemical plants with respect to emissions from flares. On April 21, 2014, we
received a Clean Air Act Section 114 Information Request from the EPA which sought information
regarding flares at the Calvert City facility and certain Lake Charles facilities. The EPA has informed
us that the information provided leads the EPA to believe 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 us to take corrective actions relating to the alleged noncompliance. We believe the
resolution of these matters may require the payment of a monetary sanction in excess of $1 million.

We do not believe that the resolution of these flare matters will have a material adverse effect on our

financial condition, results of operations or cash flows.

Also see our discussion of our environmental matters contained in Item 1A, “Risk Factors” below, Item 3,
“Legal Proceedings” below and Note 22 to our consolidated financial statements included in Item 8 of this Form
10-K.

Our employees are distributed across 16 countries. As of December 31, 2021, approximately 72% were

employed in the United States. Approximately 24.7% of our employees are represented by labor unions, and all
of these union employees are working under collective bargaining agreements that expire at various times
through 2026. We have multiple collective bargaining agreements in Europe, North America and Asia, covering
different groups of our work force. There were no strikes, lockouts or work stoppages in 2021, and we believe
that our relationship with our employees and unions is open and positive.

Attracting, developing and retaining talented people is crucial to executing our strategy. Our ability to

recruit and retain such talent depends on a number of factors, including compensation and benefits, career
opportunities and work environment. We provide our employees with competitive compensation packages,
development programs that enable continued learning and growth, and comprehensive and competitive benefit
packages worldwide. Our compensation and benefits arrangements generally are tailored to local markets of
operation.

Health and Safety

The health and safety of our employees and our operations is our highest priority. Our health and safety

programs are designed around global standards with appropriate variations addressing the multiple jurisdictions
and regulations, specific hazards and unique working environments of our manufacturing, research and
development, and administrative office locations. We require each of our locations to perform regular safety
audits to ensure proper safety policies, program procedures, analyses and training are in place.

Our focus on safety starts at the top with our Board of Directors. Safety is a key performance indicator that
is reported on and discussed at every Board meeting. Our Health, Safety and Environment (“HSE”) team plays a
pivotal role in overseeing all related policy protections, risk identification and other aspects of our business.

Several of our U.S. manufacturing sites have been recognized by the U.S. Occupational Safety & Health

Administration’s (“OSHA”) Voluntary Protection Program (“VPP”) for their low injury rates, employee

13

engagement and safety programs. All of our chemical sites in Germany satisfy the Deutsche Industrie Norm ISO
45001 certification program, which is comparable to VPP.

With respect to the ongoing COVID-19 pandemic, we have adopted safety guidelines and practices,
including safety and health training for existing and new employees, remote working, health screening of
employees, contact tracing for reported exposure, enforcing self-isolation after exposure, provisions for mask
wearing, modifications to the in-office work environment, social distancing, increased sanitation stations and
increased cleaning of offices and workstations.

Intellectual Property and Technology

We rely upon both trademark and service mark protection to protect our brands, and have registered or

applied to register many of these on a world-wide basis. We have over 1000 active and pending trademark
registrations worldwide for our various business segments. We also rely on a combination of patents and
un-patented proprietary know-how and trade secrets to preserve our competitive technology position in the
market. We have over 900 issued patents and pending patent applications in the United States and several other
countries. While some of our production capacity operates under licenses from third parties, other parts of our
production operate under technology that was developed internally. Consequently, we offer our own
independently developed technology for licensing when the opportunity makes sense on a commercial basis.
Although the Company considers its patents, licenses, trademarks and trade secrets in the aggregate to constitute
a valuable asset that provides competitive advantage to us, we do not regard any one of our businesses as being
materially dependent upon any single or group of related patents, trademarks, licenses, or trade secrets.

Item 1A. Risk Factors

Risk Factors Relating to Our Operations

The impact and effects of public health crises, pandemics and epidemics, including the ongoing coronavirus
(“COVID-19”) pandemic, could materially adversely affect our business, financial condition and results of
operations.

Public health crises, pandemics and epidemics, such as the COVID-19 pandemic, could materially
adversely affect our business, financial condition and results of operations. The COVID-19 pandemic has
resulted in authorities implementing numerous measures to try to contain the disease, such as travel bans and
restrictions, quarantines, shelter-in-place orders and shutdowns, among others. There have been widespread

14

adverse impacts on the global economy, many of our facilities and on our employees, customers and suppliers.
We have encountered supply chain constraints and disruptions and workforce availability issues as a result of
COVID-19 related actions.

Despite the availability of vaccines in all of the jurisdictions in which we operate, the COVID-19 pandemic
may continue unabated or worsen, including as a result of the emergence of more infectious strains of the virus or
vaccine hesitancy. The perceived risk of infection and health risks associated with COVID-19 has and will
continue to alter behaviors of consumers and policies of companies around the world.

We 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
governmental and regulatory authorities. We may take further actions as required by government authorities or
that we determine are in the best interests of our employees, customers, partners, and suppliers. However, the
inability to operate our facilities or the reduced demand for our products could adversely affect our business.
There is no certainty that such measures will be sufficient to mitigate the risks posed by the virus, and our ability
to perform certain functions could be harmed. The ultimate extent of the impact of COVID-19 on our business,
financial condition and results of operations will depend largely on future developments, including the duration
and spread of COVID-19 within the United States and the parts of the world in which we operate, the impact of
governmental actions designed to prevent the spread of COVID-19 and the development, availability, timely
distribution and acceptance of effective treatments and vaccines worldwide, all of which are highly uncertain and
cannot be predicted with certainty at this time.

Cyclicality in the petrochemical industry has in the past, and may in the future, result in reduced operating
margins or operating losses.

Our historical operating results reflect the cyclical and volatile nature of the petrochemical industry. The
industry is mature and capital intensive. Margins in this industry are sensitive to supply and demand balances
both domestically and internationally, which historically have been cyclical. The cycles are generally
characterized by periods of tight supply, leading to high operating rates and margins, followed by periods of
oversupply primarily resulting from excess new capacity additions, leading to reduced operating rates and lower
margins.

Moreover, profitability in the petrochemical industry is affected by the worldwide level of demand along

with vigorous price competition which may intensify due to, among other things, new industry capacity. In
general, weak economic conditions reduce demand and put pressure on margins. It is not possible to predict
accurately the supply and demand balances, market conditions and other factors that will affect industry
operating margins in the future.

New capacity additions, principally of olefins in North America, Asia and the Middle East, a number of

which have been recently completed, may lead to periods of over-supply and lower profitability. As a result, our
Performance and Essential Materials segment operating margins may be negatively impacted.

We sell commodity products in highly competitive markets and face significant competition and price
pressure.

We sell our products in highly competitive markets. Due to the commodity nature of many of our products,

competition in these markets is based primarily on price and to a lesser extent on performance, product quality,
product deliverability and customer service. As a result, we generally are not able to protect our market position

15

for these products by product differentiation and may not be able to pass on cost increases to our customers.
Accordingly, increases in raw material and other costs may not necessarily correlate with changes in prices for
these products, either in the direction of the price change or in magnitude. Specifically, timing differences in
pricing between raw material prices, which may change daily, and contract product prices, which in many cases
are negotiated monthly or less often, sometimes with an additional lag in effective dates for increases, have had
and may continue to have a negative effect on profitability. Significant volatility in raw material costs tends to
place pressure on product margins as sales price increases could lag behind raw material cost increases.
Conversely, when raw material costs decrease, customers could seek relief in the form of lower sales prices.

Volatility in costs of raw materials and energy may result in increased operating expenses and adversely affect
our results of operations and cash flows.

Significant variations in the costs and availability of raw materials and energy may negatively affect our

results of operations. These costs have risen significantly in the past due primarily to oil and natural gas cost
increases. We purchase significant amounts of ethane feedstock, natural gas, ethylene and salt to produce several
basic chemicals. We also purchase significant amounts of electricity to supply the energy required in our
production processes. The cost of these raw materials and energy, in the aggregate, represents a substantial
portion of our operating expenses. The prices of raw materials and energy generally follow price trends of, and
vary with market conditions for, crude oil and natural gas, which are highly volatile and cyclical, as well as the
ability of domestic producers to export natural gas liquids, ethane and ethylene. Changes to regulatory policies
applicable to the German energy sector for industrial users have contributed to higher prices for industrial users
of energy in the past and may continue to do so in the future. Our results of operations have been and could in the
future be significantly affected by increases in these costs.

Price increases increase our working capital needs and, accordingly, can adversely affect our liquidity and
cash flows. In addition, because we utilize the first-in, first-out (“FIFO”) method of inventory accounting, during
periods of falling raw material prices and declining sales prices, our results of operations for a particular
reporting period could be negatively impacted as the lower sales prices would be reflected in operating income
more quickly than the corresponding drop in feedstock costs. We use derivative instruments in an attempt to
reduce price volatility risk on some feedstock commodities. In the future, we may decide not to hedge any of our
raw material costs or any hedges we enter into may not have successful results. Also, our hedging activities
involve credit risk associated with our hedging counterparties, and a deterioration in the financial markets could
adversely affect our hedging counterparties and their abilities to fulfill their obligations to us.

Lower prices of crude oil, such as those experienced from the third quarter of 2014 through 2020, led to a

reduction in the cost advantage for natural gas liquids-based ethylene crackers in North America, such as ours, as
compared to naphtha-based ethylene crackers. As a result, our margins and cash flows were negatively impacted.
Lower crude oil and natural gas prices could lead to a reduction in hydraulic fracturing in the United States,
which could reduce the availability of feedstock and increase prices of feedstock for our operations. Higher
natural gas prices could also adversely affect our ability to export products that we produce in the United States.
In addition to the impact that this has on our exports from the United States, reduced competitiveness of U.S.
producers also has in the past increased the availability of chemicals in North America, as U.S. production that
would otherwise have been sold overseas was instead offered for sale domestically, resulting in excess supply
and lower prices in North America. We could also face the threat of imported products from countries that have a
cost advantage. Furthermore, additional export storage facilities for natural gas liquids, ethane and ethylene may
lead to higher exports of such products from the United States or greater restrictions on hydraulic fracturing
could restrict the availability of our raw materials in the United States, thereby increasing our costs.

16

External factors beyond our control can cause fluctuations in demand for our products and in our prices and
margins, which may negatively affect our results of operations and cash flows.

External factors beyond our control can cause volatility in raw material prices, demand for our products,

product prices and volumes and deterioration in operating margins. These factors can also magnify the impact of
economic cycles on our business and results of operations. Examples of external factors include:

general economic conditions, including in the United States, Europe and Asia;

new capacity additions in North America, Europe, Asia and the Middle East;

the level of business activity in the industries that use our products;

competitor action;

technological innovations;

currency fluctuations;

increases in interest rates;

international events and circumstances;

pandemics and other public health threats and efforts to contain their transmission;

war, sabotage, terrorism and civil unrest;

governmental regulation, including in the United States, Europe and Asia;

public attitude towards climate change and safety, health and the environment;

perceptions of our products by potential buyers of our products, as well as the public generally, and
related changes in behavior, including with respect to recycling;

severe weather and natural disasters; and

credit worthiness of customers and vendors.

A number of our products are highly dependent on durable goods markets, such as housing and

construction, which are themselves particularly cyclical. Weakness in the U.S. residential housing market and
economic weakness in Europe could have an adverse effect on demand and margins for our products.

We may reduce production at or idle a facility for an extended period of time or exit a business because of

high raw material prices, an oversupply of a particular product and/or a lack of demand for that particular
product, which makes production uneconomical. Temporary outages sometimes last for several quarters or, in
certain cases, longer and cause us to incur costs, including the expenses of maintaining and restarting these
facilities. Factors such as increases in raw material costs or lower demand in the future may cause us to further
reduce operating rates, idle facilities or exit uncompetitive businesses.

A lower level of economic activity in the United States, Europe or globally could result in a decline in
demand for our products, which could adversely affect our net sales and margins and limit our future growth
prospects. In addition, these risks could cause increased instability in the financial and insurance markets and
could adversely affect our ability to access capital and to obtain insurance coverage that we consider adequate or
is otherwise required by our contracts with third parties.

17

The housing market may not continue to grow at the same rate, or may decline, and any decline in the
homebuilding industry may adversely affect our operating results.

We cannot predict whether and to what extent the housing market in the United States will continue to
grow, particularly if interest rates for mortgage loans and construction costs rise. Other factors that might impact
growth in the homebuilding industry include uncertainty in domestic and international financial, credit and
consumer lending markets amid slow economic growth or recessionary conditions in various regions or
industries around the world, including as a result of the COVID-19 pandemic, tight lending standards and
practices for mortgage loans that limit consumers’ ability to qualify for mortgage financing to purchase a home,
higher home prices, population declines or slower rates of population growth or U.S. Federal Reserve policy
changes. Given these factors, we can provide no assurance that the present housing market will continue to be
strong.

If there is limited economic growth, a decline in employment and consumer income, a general change in

consumer behavior, including as a result of the COVID-19 pandemic, and/or tightening of mortgage lending
standards, practices and regulation, or if interest rates for mortgage loans or home prices rise, there could be a
corresponding adverse effect on our financial condition, results of operations or cash flows, including, but not
limited to, the amount of revenues or profits we generate in our housing and infrastructure products segment.

We operate internationally and are subject to related risks, including exchange rate fluctuations, exchange
controls, political risk and other risks relating to international operations.

We operate internationally and are subject to the risks of doing business on a global basis. These risks
include, but are not limited to, fluctuations in currency exchange rates, currency devaluations, imposition or the
threat of trade barriers (which could, among other things, negatively impact our ability to export our products
outside of the United States), imposition or the threat of tariffs and duties (which could, among other things, lead
to lower demand for our products outside of the United States), restrictions on the transfer of funds, changes in
law and regulatory requirements, involvement in judicial proceedings in unfavorable jurisdictions, economic
instability and disruptions, political unrest and epidemics. U.S. foreign trade policies could lead to the imposition
of additional trade barriers and tariffs on us in foreign jurisdictions. Our operating results could be negatively
affected by any of these risks.

Our inability to compete successfully may reduce our operating profits.

The industries in which we operate are highly competitive. Historically, there have been a number of
mergers, acquisitions, spin-offs and joint ventures in the industry. This restructuring activity has resulted in fewer
but more competitive producers, many of which are larger than we are and have greater financial resources than
we do. Among our competitors are some of the world’s largest chemical companies and chemical industry joint
ventures. Competition within the petrochemical industry and in the manufacturing of housing and infrastructure
products is affected by a variety of factors, including:

(cid:129)

(cid:129)

product price;

balance of product supply/demand;

(cid:129) material, technology and process innovation;

(cid:129)

(cid:129)

(cid:129)

technical support and customer service;

quality;

reliability of raw material and utility supply;

18

(cid:129)

(cid:129)

availability of potential substitute materials; and

product performance.

Changes in the competitive environment could have a material adverse effect on our business and our

operations. These changes could include:

(cid:129)

(cid:129)

(cid:129)

(cid:129)

(cid:129)

(cid:129)

(cid:129)

the emergence of new domestic and international competitors;

the rate of capacity additions by competitors;

the additions of export storage facilities for natural gas liquids, ethane and ethylene;

changes in customer base due to mergers;

the intensification of price competition in our markets;

the introduction of new or substitute products by competitors; and

the technological innovations of competitors.

Our production facilities process some volatile and hazardous materials that subject us to operating risks that
could adversely affect our operating results.

We have manufacturing sites in North America, Europe and Asia. Our operations are subject to the usual

hazards associated with chemical, plastics, housing and infrastructure products manufacturing and the related
use, storage, transportation and disposal of feedstocks, products and wastes, including:

(cid:129)

(cid:129)

(cid:129)

(cid:129)

pipeline leaks and ruptures;

explosions;

fires;

severe weather and natural disasters;

(cid:129) mechanical failure;

(cid:129)

(cid:129)

(cid:129)

(cid:129)

(cid:129)

(cid:129)

(cid:129)

(cid:129)

(cid:129)

(cid:129)

unscheduled downtime;

labor difficulties;

transportation interruptions;

transportation accidents involving our products;

remediation complications;

chemical spills, discharges or releases of toxic or hazardous substances or gases;

other environmental risks;

sabotage;

terrorist attacks; and

political unrest.

Global climate change could result in heightened hurricane activity in the Gulf of Mexico and other
weather and natural disaster hazards worldwide. If this materializes, severe weather and natural disaster hazards
could pose an even greater risk for our facilities, particularly those in Louisiana.

19

All these hazards can cause personal injury and loss of life, catastrophic damage to or destruction of
property and equipment and environmental damage, and may result in a suspension of operations and the
imposition of civil or criminal penalties. We are from time to time subject to environmental claims brought by
governmental entities or third parties. A loss or shutdown over an extended period of operations at any one of our
chemical manufacturing facilities would have a material adverse effect on us. We maintain property, business
interruption and casualty insurance that we believe is in accordance with customary industry practices, but we
cannot be fully insured against all potential hazards incident to our business, including losses resulting from war
risks or terrorist acts. As a result of market conditions, premiums and deductibles for certain insurance policies
can increase substantially and, in some instances, certain insurance may become unavailable or available only for
reduced amounts of coverage. If we were to incur a significant liability for which we were not fully insured, it
could have a material adverse effect on our financial condition, results of operations or cash flows.

We are exposed to significant losses from products liability, personal injury and other claims relating to the
products we manufacture. Additionally, individuals currently seek, and likely will continue to seek, damages for
alleged personal injury or property damage due to alleged exposure to chemicals at our facilities or to chemicals
otherwise owned, controlled or manufactured by us. We are also subject to present and future claims with respect
to workplace exposure, workers’ compensation and other matters. Any such claims, whether with or without
merit, could be time consuming, expensive to defend and could divert management’s attention and resources. We
maintain and expect to continue to maintain insurance for products liability, workplace exposure, workers’
compensation and other claims, but the amount and scope of such insurance may not be adequate or available to
cover a claim that is successfully asserted against us. In addition, such insurance could become more expensive
and difficult to maintain and may not be available to us on commercially reasonable terms or at all. The results of
any future litigation or claims are inherently unpredictable, but such outcomes could have a material adverse
effect on our financial condition, results of operations or cash flows.

We rely on a limited number of outside suppliers for specified feedstocks and services.

We obtain a significant portion of our raw materials from a few key suppliers. If any of these suppliers is

unable to meet its obligations under any present or future supply agreements, we may be forced to pay higher
prices to obtain the necessary raw materials. Any interruption of supply or any price increase of raw materials
could have a material adverse effect on our business and results of operations. A vendor may choose, subject to
existing contracts, to modify its relationship due to general economic concerns or concerns relating to the vendor
or us, at any time. Any significant change in the terms that we have with our key suppliers, or any significant
additional requirements from our suppliers that we provide them additional security in the form of prepayments
or with letters of credits, could materially adversely affect our financial condition, results of operations or cash
flows.

We rely heavily on third party transportation, which subjects us to risks and costs that we cannot control. Such
risks and costs may materially adversely affect our operations.

We rely heavily on railroads, barges, pipelines, ships, trucks and other shipping companies to transport raw
materials to the manufacturing facilities used by our businesses and to ship finished products to customers. These
transport operations are subject to various hazards and risks, including extreme weather conditions, work
stoppages and operating hazards (including pipeline leaks and ruptures and storage tank leaks), as well as
interstate transportation regulations. In addition, the methods of transportation we utilize, including shipping
chlorine and other chemicals by railroad, may be subject to additional, more stringent and more costly
regulations in the future. If we are delayed or unable to ship finished products or unable to obtain raw materials

20

as a result of any such new regulations or public policy changes related to transportation safety, or these
transportation companies fail to operate properly, or if there were significant changes in the cost of these services
due to new or additional regulations, or otherwise, we may not be able to arrange efficient alternatives and timely
means to obtain raw materials or ship goods, which could result in a material adverse effect on our business and
results of operations.

We may pursue acquisitions, dispositions and joint ventures and/or other transactions that may impact our
results of operations and financial condition. We may have difficulties integrating the operations of the Boral
Target Companies, LASCO, Dimex, Hexion epoxy, and future acquired businesses.

We seek opportunities to maximize efficiency and create stockholder value through various transactions.

These transactions may include domestic and international business combinations, purchases or sales of assets or
contractual arrangements or joint ventures. In this regard, we regularly consider acquisition opportunities that
would be consistent or complementary to our existing business strategies. To the extent permitted under our
credit facility, the indenture governing our senior notes and other debt agreements, some of these transactions
may be financed by additional borrowings by us. Although we would pursue these transactions because we
expect them to yield longer-term benefits if the efficiencies and synergies we expect are realized, they could
adversely affect our results of operations in the short term because of the costs associated with such transactions
and because they may divert management’s attention from existing business operations. These transactions may
not yield the business benefits, synergies or financial benefits anticipated by management. Integration of acquired
operations could lead to restructuring charges or other costs.

Our ability to realize the anticipated benefits of the Acquisitions will depend, to a large extent, on our
ability to integrate our business with the businesses of the Boral Target Companies, LASCO, Dimex and Hexion
epoxy. The combination of such independent businesses is a complex, costly and time-consuming process. As a
result, we have devoted, and will continue to devote significant management attention and resources to
integrating each of the Boral Target Companies’, LASCO’s, Dimex’s and Hexion epoxy’s business practices and
operations with our existing business practices and operations. The integration process may disrupt the
businesses and, if implemented ineffectively or if impacted by unforeseen negative economic or market
conditions or other factors, we may not realize the full anticipated benefits of the Acquisitions. Our failure to
meet the challenges involved in integrating such businesses could adversely affect our results of operations.

In addition, the overall integration of the businesses may result in material unanticipated problems,
expenses, liabilities, competitive responses, loss of customer relationships, or diversion of management’s
attention. Even if the operations of our businesses and the businesses of the Boral Target Companies, LASCO,
Dimex and Hexion epoxy are integrated successfully, we may not realize the full benefits of the Acquisitions,
including the synergies, cost savings or sales or growth opportunities that we expect. These benefits may not be
achieved within the anticipated time frame, or at all. Furthermore, additional unanticipated costs may be incurred
in the integration of the businesses. All of these factors could decrease or delay the expected benefits of the
Acquisitions and negatively impact us.

If we are unable to integrate or to successfully manage businesses that we may acquire in the future, our

business, financial condition and results of operations could be adversely affected. We may not be able to realize
the operating efficiencies, synergies, cost savings or other benefits expected from acquisitions for a number of
reasons, including the following:

(cid:129)

we may fail to integrate the businesses we acquire into a cohesive, efficient enterprise;

21

(cid:129)

our resources, including management resources, are limited and may be strained if we engage in a
large acquisition or significant number of acquisitions, and acquisitions may divert our
management’s attention from initiating or carrying out programs to save costs or enhance revenues;
and

(cid:129)

our failure to retain key employees and contracts of the businesses we acquire.

Our operations and assets are subject to extensive environmental, health and safety laws and regulations.

We use large quantities of hazardous substances and generate hazardous wastes and emissions in our
manufacturing operations. Due to the associated quantities of hazardous substances and wastes, our industry is
highly regulated and monitored by various environmental regulatory authorities such as the EPA, federal or state
analogs in other countries and the European Union, which promulgated the Industrial Emission Directive
(“IED”). As such, we are subject to extensive international, national, state and local laws, regulations and
directives pertaining to pollution and protection of the environment, health and safety, which govern, among
other things, emissions to the air, discharges onto land or waters, the maintenance of safe conditions in the
workplace, the remediation of contaminated sites, and the generation, handling, storage, transportation, treatment
and disposal of waste materials. Some of these laws, regulations and directives are subject to varying and
conflicting interpretations. Many of these laws, regulations and directives provide for substantial fines and
potential criminal sanctions for violations and require the installation of costly pollution control equipment or
operational changes to limit pollution emissions or reduce the likelihood or impact of hazardous substance
releases, whether permitted or not. For example, all of our petrochemical facilities in the United States and
Europe may require improvements to comply with certain changes in process safety management requirements.

New laws, rules and regulations as well as changes to laws, rules and regulations may also affect us. For

example, on April 17, 2012, the EPA promulgated maximum achievable control technology standards for major
sources and generally available control technology standards for area sources of PVC production. The rule sets
emission limits and work practice standards for total organic air toxics and for three specific air toxics: vinyl
chloride, chlorinated di-benzo dioxins and furans and hydrogen chloride and includes requirements to
demonstrate initial and continuous compliance with the emission standards. In June 2012, the EPA received
petitions for reconsideration of the rule. On November 9, 2020, the EPA proposed rule amendments to address
issues raised in the petitions for reconsideration. While this rule is the subject of legal challenge and EPA
reconsideration, the rule has not been stayed. Although we cannot predict the outcome or timing of the legal
challenges or EPA reconsideration, the EPA’s proposed rule amendments could require us to incur further capital
expenditures, or increase our operating costs, to levels higher than what we have previously estimated.

In March 2011, the EPA proposed amendments to the national emission standards for hazardous air

pollutants (“NESHAPs”) for mercury emissions from mercury cell chlor-alkali plants. These proposed
amendments would require improvements in work practices to reduce fugitive mercury emissions. In addition, on
January 8, 2021, the EPA proposed amendments to the 2003 NESHAPs for mercury cell chlor-alkali plants
residual risk and technology review. Among other things, the proposed rule would require work practice
standards for the cell rooms and instrumental monitoring of cell room fugitive emissions, modify regulatory
provisions regarding startup, shutdown, and malfunctions, and add standards for fugitive chlorine emissions from
mercury cell chlor-alkali plants, which are not currently regulated under the NESHAP. The EPA extended the
public comment period on the proposed rule to March 24, 2021. The EPA has yet to publish the final rule and we
cannot predict the timing or content of the final regulation. We operate a mercury cell production unit at our
Natrium facility. If the proposed amendments were finalized, they could result in additional restrictions on our
operations or increased compliance costs.

22

Our operations 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. 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.

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 GHG emissions. In the European Union, the Emissions Trading Scheme obligates
certain emitters to obtain GHG emission allowances to comply with a cap and trade system for GHG emissions.
In addition, the European Union has committed to reduce domestic GHG emissions by at least 55% below the
1990 level by 2030. As our chemical manufacturing processes result in GHG emissions, these and other GHG
laws and regulations could affect our costs of doing business.

Similarly, the Toxic Substances Control Act (“TSCA”) imposes reporting, record-keeping and testing

requirements, and restrictions relating to the production, handling, and use of chemical substances. The TSCA
reform legislation enacted in June 2016 expanded the EPA’s authority to review and regulate new and existing
chemicals. Under the reform legislation, the EPA is required to, among other things, undertake rule making
within statutory time frames related to: (1) chemical risk evaluation, designation and management; (2) reporting
of mercury supply, use and trade; and (3) management of persistent, bioaccumulative, and toxic chemical
substances (“PBTs”). In response to this mandate, the EPA issued rules establishing the EPA’s process and
criteria for identifying high priority chemicals for risk evaluation and setting the EPA’s approach for determining
whether these high priority chemicals present an unreasonable risk to health or the environment. Pursuant to its
rules, the EPA designated certain chemical substances as high priority for risk evaluation. We manufacture
several of these chemical substances. Although we cannot predict with certainty the extent of our future liabilities
and costs at this time, we do not anticipate that the evaluation of these chemical substances will have a material
adverse effect on our business, financial condition, operating results or cash flows. In addition, the TSCA
inventory reset rule required industry reporting of chemicals manufactured or processed in the United States over
a 10-year period ending in 2016. This reporting is used by the EPA to identify which chemicals are active or
inactive on the TSCA Inventory. Beginning in 2019, chemical manufacturers and processors are required to
notify and obtain approval by the EPA before reintroducing inactive chemicals into commerce. A final mercury
reporting rule published in June 2018 requires manufacturers, including manufacturers who use mercury in a

23

manufacturing process, to report information about their mercury supply, use and trade. The first periodic
reporting deadline under the mercury reporting rule was July 1, 2019. The EPA used the information collected to
develop an inventory of mercury and mercury-added products as well as mercury-use manufacturing processes.
The EPA also recommended actions and rule amendments based on the collected information. We cannot predict
the timing or content of these actions or amendments, or their ultimate cost to, or impact on us.

On June 28, 2021, the EPA proposed reporting and recordkeeping requirements for Per- and
Polyfluoroalkyl Substances (“PFAS”) under TSCA. The proposed rule would require manufacturers, and
importers, that have manufactured or imported PFAS chemicals since January 1, 2011, to electronically report
information regarding PFAS uses, production volumes, disposal, exposures, and hazards. The EPA has not yet
issued a final rule; however, PFAS chemicals have come under increased scrutiny by federal, state, and local
governments. For example, many states have banned the use of PFAS in certain consumer products and set
Maximum Contaminant Levels for PFAS in drinking water. The EPA is also considering regulating certain PFAS
chemicals under the Safe Drinking Water Act, and has announced that it intends to develop a proposed National
Primary Drinking Water Regulation for perfluorooctanesulfonic acid (“PFOS”) and perfluorooctanoic acid
(“PFOA”), two of the most common PFAS chemicals. We are unable to predict the impact these requirements
and concepts may have on our future costs of compliance.

Under the IED, European Union member state governments are expected to adopt rules and implement

environmental permitting programs relating to air, water and waste for industrial facilities. In this context,
concepts such as the “best available technique” are being explored. Future implementation of these concepts may
result in technical modifications in our European facilities. In addition, under the Environmental Liability
Directive, European Union member states can require the remediation of soil and groundwater contamination in
certain circumstances, under the “polluter pays principle.” We are unable to predict the impact these
requirements and concepts may have on our future costs of compliance.

Local, state, federal and foreign governments have increasingly proposed or implemented restrictions on
certain plastic-based products, including single-use plastics and plastic food packaging. Plastics have also faced
increased public scrutiny due to negative coverage of plastic waste in the environment. Increased regulation on
the use of plastics could cause reduced demand for our polyethylene products, which could adversely affect our
business, operating results and financial condition.

These rules or future new, amended or proposed laws or rules could increase our costs or reduce our
production, which could have a material adverse effect on our business, financial condition, operating results or
cash flows. In addition, we cannot accurately predict future developments, such as increasingly strict
environmental and safety laws or regulations, and inspection and enforcement policies, as well as resulting
higher compliance costs, which might affect the handling, manufacture, use, emission, disposal or remediation of
products, other materials or hazardous and non-hazardous waste, and we cannot predict with certainty the extent
of our future liabilities and costs under environmental, health and safety laws and regulations. These liabilities
and costs may be material.

We also may face liability for alleged personal injury or property damage due to exposure to chemicals or

other hazardous substances at our facilities or to chemicals that we otherwise manufacture, handle or own.
Although these types of claims have not historically had a material impact on our operations, a significant
increase in the success of these types of claims could have a material adverse effect on our business, financial
condition, operating results or cash flows.

24

Environmental laws may have a significant effect on the nature and scope of, and responsibility for,
cleanup of contamination at our current and former operating facilities, the costs of transportation and storage of
raw materials and finished products, the costs of reducing emissions and the costs of the storage and disposal of
wastewater. The U.S. Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”),
similar state laws and certain European directives impose joint and several liability for the costs of remedial
investigations and actions on the entities that generated waste, arranged for disposal of the wastes, transported to
or selected the disposal sites and the past and present owners and operators of such sites. All such potentially
responsible parties (or any one of them, including us) may be required to bear all of such costs regardless of fault,
legality of the original disposal or ownership of the disposal site. In addition, CERCLA, similar state laws and
certain European directives could impose liability for damages to natural resources caused by contamination.

Although we seek to take preventive action, our operations are inherently subject to accidental spills,
discharges or other releases of hazardous substances that may make us liable to governmental entities or private
parties. This may involve contamination associated with our current and former facilities, facilities to which we
sent wastes or by-products for treatment or disposal and other contamination. Accidental discharges may occur in
the future, future action may be taken in connection with past discharges, governmental agencies may assess
damages or penalties against us in connection with any past or future contamination, or third parties may assert
claims against us for damages allegedly arising out of any past or future contamination. In addition, we may be
liable for existing contamination related to certain of our facilities for which, in some cases, we believe third
parties are liable in the event such third parties fail to perform their obligations.

Capital projects are subject to risks, including delays and cost overruns, which could have an adverse impact
on our financial condition and results of operations.

We have capital expansion plans for our facilities. Expansion projects may be subject to delays or cost

overruns, including delays or cost overruns resulting from any one or more of the following:

unexpectedly long delivery times for, or shortages of, key equipment, parts or materials;

shortages of skilled labor and other personnel necessary to perform the work;

delays and performance issues;

failures or delays of third-party equipment vendors or service providers;

unforeseen increases in the cost of equipment, labor and raw materials;

work stoppages and other labor disputes;

unanticipated actual or purported change orders;

disputes with contractors and suppliers;

design and engineering problems;

latent damages or deterioration to equipment and machinery in excess of engineering estimates and
assumptions;

financial or other difficulties of our contractors and suppliers;

sabotage;

terrorist attacks;

interference from adverse weather conditions; and

difficulties in obtaining necessary permits or in meeting permit conditions.

25

Significant cost overruns or delays could materially affect our financial condition and results of operations.

Additionally, actual capital expenditures could materially exceed our planned capital expenditures.

Our level of debt could adversely affect our ability to operate our business.

As of December 31, 2021, our indebtedness, including the current portion, totaled $5.2 billion, and our debt

represented approximately 38% of our total capitalization. Our annual interest expense for 2021 was
$176 million, net of interest capitalized of $3 million. Our level of debt and the limitations imposed on us by our
existing or future debt agreements could have significant consequences on our business and future prospects,
including the following:

(cid:129)

(cid:129)

(cid:129)

(cid:129)

(cid:129)

(cid:129)

a portion of our cash flows from operations will be dedicated to the payment of interest and principal
on our debt and will not be available for other purposes;

we may not be able to obtain necessary financing in the future for working capital, capital
expenditures, acquisitions, debt service requirements or other purposes;

our less leveraged competitors could have a competitive advantage because they have greater
flexibility to utilize their cash flows to improve their operations;

we may be exposed to risks inherent in interest rate fluctuations because some of our borrowings are
at variable rates of interest, which would result in higher interest expense in the event of increases in
interest rates;

we could be vulnerable in the event of a downturn in our business that would leave us less able to
take advantage of significant business opportunities and to react to changes in our business and in
market or industry conditions; and

should we pursue additional expansions of existing assets or acquisition of third-party assets, we may
not be able to obtain additional liquidity at cost effective interest rates.

These factors could be magnified or accelerated to the extent we were to finance future acquisitions with

significant amounts of debt.

To service our indebtedness and fund our capital requirements, we will require a significant amount of cash.
Our ability to generate cash depends on many factors beyond our control.

Our ability to make payments on and to refinance our indebtedness and to fund planned capital
expenditures and pay cash dividends will depend on our ability to generate cash in the future, including any
distributions that we may receive from Westlake Partners. This is subject to general economic, financial,
currency, competitive, legislative, regulatory and other factors that are beyond our control.

Our business may not generate sufficient cash flows from operations, we may not receive sufficient
distributions from Westlake Partners, and currently anticipated cost savings and operating improvements may not
be realized on schedule. We also generate revenues denominated in currencies other than that of our indebtedness
and may have difficulty converting those revenues into the currency of our indebtedness. We may need to
refinance all or a portion of our indebtedness on or before maturity. In addition, we may not be able to refinance
any of our indebtedness, including our credit facility and our senior notes, on commercially reasonable terms or
at all. All of these factors could be magnified if we were to finance any future acquisitions with significant
amounts of debt.

26

The Credit Agreement and the indenture governing certain of our senior notes impose significant operating
and financial restrictions, which may prevent us from capitalizing on business opportunities and taking some
actions.

The Credit Agreement and the indenture governing certain of our senior notes impose significant operating

and financial restrictions on us. These restrictions limit our ability to:

(cid:129)

(cid:129)

(cid:129)

(cid:129)

incur additional indebtedness;

create liens;

sell all or substantially all of our assets or consolidate or merge with or into other companies; and

engage in sale-leaseback transactions.

These limitations are subject to a number of important qualifications and exceptions. The Credit

Agreement also requires us to maintain a quarterly total leverage ratio.

These covenants may adversely affect our ability to finance future business opportunities or acquisitions. A

breach of any of these covenants could result in a default in respect of the related debt. If a default occurred, the
relevant lenders could elect to declare the debt, together with accrued interest and other fees, to be immediately
due and payable. In addition, any acceleration of debt under the Credit Agreement will constitute a default under
some of our other debt, including the indentures governing our senior notes.

Our participation in joint ventures and similar arrangements exposes us to a number of risks, including risks
of shared control.

We are party to several joint ventures and similar arrangements, including an investment, together with

Lotte Chemical USA Corporation (“Lotte”), in a joint venture, LACC, LLC (“LACC”), to build and operate an
ethylene facility. Our participation in joint ventures and similar arrangements, by their nature, requires us to
share control with unaffiliated third parties. If there are differences in views among joint venture participants in
how to operate a joint venture that result in delayed decisions or the failure to make decisions, or our joint
venture partners do not fulfill their obligations, the affected joint venture may not be able to operate according to
its business plan and fulfill its obligations. In that case, we may be required to write down the value of our
investment in a joint venture, increase the level of financial or other commitments to the joint venture or, if we
have contractual agreements with the joint venture, our operations may be materially adversely affected. Any of
the foregoing could have a material adverse effect on our financial condition, results of operations or cash flows.

Our operations could be adversely affected by labor relations.

The vast majority of our employees in Europe and Asia, and some of our 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.

We have certain material pension and other post-retirement employment benefit (“OPEB”) obligations.
Future funding obligations related to these obligations could restrict cash available for our operations, capital
expenditures or other requirements or require us to borrow additional funds.

We have U.S. and non-U.S. defined benefit pension plans covering certain current and former employees.

Certain non-U.S. defined benefit plans associated with our European operations have not been funded and we are
not obligated to fund those plans under applicable law. As of December 31, 2021, the projected benefit

27

obligations for our pension and OPEB plans were $825 million and $62 million, respectively. The fair value of
pension investment assets was $583 million as of December 31, 2021. The total underfunded status of the
pension obligations calculated on a projected benefit obligation basis as of December 31, 2021 was $242 million,
including the Westlake Defined Benefit Plan and the Vinnolit Pension Plan (locally known as ‘Grund- und
Zusatzversorgung’ in Germany), which were underfunded by $83 million and $128 million, respectively, on an
individual plan basis.

The unfunded OPEB obligations as of December 31, 2021 were $62 million. We will require future

operating cash flows to fund our pension and OPEB obligations, which could restrict available cash for our
operations, capital expenditures and other requirements. We may also not generate sufficient cash to satisfy these
obligations, which could require us to seek funding from other sources, including through additional borrowings,
which could materially increase our outstanding debt or debt service requirements.

If our goodwill, indefinite-lived intangible assets or other intangible assets become impaired in the future, we
may be required to record non-cash charges to earnings, which could be significant.

Under GAAP, we review goodwill and indefinite-lived intangible assets for impairment on an annual basis

or more frequently if events or circumstances indicate that their carrying value may not be recoverable. Other
intangible assets are reviewed if events or circumstances indicate that their carrying value may not be
recoverable. The process of impairment testing for our goodwill and intangible assets involves a number of
judgments and estimates made by management including the fair values of assets and liabilities, future cash
flows, our interpretation of current economic indicators and market conditions, overall economic conditions and
our strategic operational plans with regards to our business units. If the judgments and estimates used in our
analysis are not realized or change due to external factors, then actual results may not be consistent with these
judgments and estimates, and our goodwill and intangible assets may become impaired in future periods. If our
goodwill, indefinite-lived intangible assets or other intangible assets are determined to be impaired in the future,
we may be required to record non-cash charges to earnings during the period in which the impairment is
determined, which could be significant and have an adverse effect on our financial condition and results of
operations.

Failure to adequately protect critical data and technology systems could materially affect our operations.

Information technology system failures, network disruptions and breaches of data security due to internal

or external factors including cyber-attacks could disrupt our operations by causing delays or cancellation of
customer orders, impede the manufacture or shipment of products or cause standard business processes to
become ineffective, resulting in the unintentional disclosure of information or damage to our reputation. Cyber-
attacks could include, but are not limited to, ransomware attacks, malicious software, attempts to gain
unauthorized access to our data and the unauthorized release, corruption or loss of our data and personal
information, interruptions in communication, loss of our intellectual property or theft of our sensitive or
proprietary technology, loss or damage to our data delivery systems, or other cybersecurity and infrastructure
systems, including our property and equipment. We have taken steps to address these risks by implementing
network security and internal control measures, including employee training, comprehensive monitoring of our
networks and systems, maintenance of backup and protective systems and disaster recovery and incident
response plans. Our employees, systems, networks, products, facilities and services remain potentially vulnerable
to sophisticated cyber-assault, especially while certain employees are working remotely during the COVID-19
pandemic, and, as such, there can be no assurance that a system failure, network disruption or data security
breach will not have a material adverse effect on our business, financial condition, operating results or cash
flows.

28

Fluctuations in foreign currency exchange and interest rates could affect our consolidated financial results.

We earn revenues, pay expenses, own assets and incur liabilities in countries using currencies other than
the U.S. dollar. Because our consolidated financial statements are presented in U.S. dollars, we must translate
revenues and expenses into U.S. dollars at the average exchange rate during each reporting period, as well as
assets and liabilities into U.S. dollars at exchange rates in effect at the end of each reporting period. Therefore,
increases or decreases in the value of the U.S. dollar against other major currencies will affect our net sales,
operating income and the value of balance sheet items denominated in foreign currencies. Because of the
geographic diversity of our operations, weaknesses in various currencies might occur in one or many of such
currencies over time. From time to time, we may use derivative financial instruments to further reduce our net
exposure to currency exchange rate fluctuations. However, fluctuations in foreign currency exchange rates, such
as the strengthening of the U.S. dollar against major currencies, including, in particular, the Euro and the
Canadian dollar, could nevertheless materially adversely affect our financial results.

In addition, we are exposed to volatility in interest rates. When appropriate, we may use derivative

financial instruments to reduce our exposure to interest rate risks. However, our financial risk management
program may not be successful in reducing the risks inherent in exposures to interest rate fluctuations.

Our property insurance has only partial coverage for acts of terrorism and, in the event of terrorist attack, we
could lose net sales and our facilities.

Our insurance carriers maintain certain exclusions for losses from terrorism from our property insurance

policies. While separate terrorism insurance coverage is available, premiums for full coverage are very
expensive, especially for chemical facilities, and the policies are subject to high deductibles. Available terrorism
coverage typically excludes coverage for losses from acts of war and from acts of foreign governments as well as
nuclear, biological and chemical attacks. We have determined that it is not economically prudent to obtain full
terrorism insurance, especially given the significant risks that are not covered by such insurance. Where feasible
we have secured some limited terrorism insurance coverage on our property where insurers have included it in
their overall programs. In the event of a terrorist attack impacting one or more of our facilities, we could lose the
net sales from the facilities and the facilities themselves, and could become liable for any contamination or for
personal or property damage due to exposure to hazardous materials caused by any catastrophic release that may
result from a terrorist attack.

Risks Related to Taxes

A change in tax laws, treaties or regulations, or their interpretation or application, could have a negative
impact on our business and results of operations.

We operate in many different countries and in many states within the United States, and we are subject to

changes in applicable tax laws, treaties or regulations in the jurisdictions in which we operate. A material change
in these tax laws, treaties or regulations, or their interpretation or application, could have a negative impact on
our business and results of operations.

29

We depend in part on distributions from Westlake Partners to generate cash for our operations, capital
expenditures, debt service and other uses. Westlake Partners’ tax treatment depends on its status as a
partnership for federal income tax purposes, and it not being subject to a material amount of entity-level
taxation. If the Internal Revenue Service (“IRS”) were to treat Westlake Partners as a corporation for federal
income tax purposes, or if Westlake Partners became subject to entity-level taxation for state tax purposes, its
cash available for distribution would be substantially reduced, which would also likely cause a substantial
reduction in the value of its common units that we hold.

The anticipated after-tax economic benefit of an investment in the common units of Westlake Partners
depends largely on Westlake Partners being treated as a partnership for U.S. federal income tax purposes. Despite
the fact that Westlake Partners is organized as a limited partnership under Delaware law, it would be treated as a
corporation for U.S. federal income tax purposes unless it satisfies a “qualifying income” requirement. Based on
Westlake Partners’ current operations and current Treasury Regulations, Westlake Partners believes it satisfies
the qualifying income requirement.

Prior to its initial public offering, Westlake Partners requested and obtained a favorable private letter ruling

from the IRS to the effect that, based on facts presented in the private letter ruling request, income from the
production, transportation, storage and marketing of ethylene and its co-products constitutes “qualifying income”
within the meaning of Section 7704 of the Internal Revenue Code of 1986, as amended. However, no ruling has
been or will be requested regarding Westlake Partners’ treatment as a partnership for U.S. federal income tax
purposes. Failing to meet the qualifying income requirement or a change in current law could cause Westlake
Partners to be treated as a corporation for U.S. federal income tax purposes or otherwise subject Westlake
Partners to taxation as an entity.

If Westlake Partners were treated as a corporation for federal income tax purposes, it would pay U.S.

federal income tax on its taxable income at the corporate tax rate. Because a tax would be imposed upon
Westlake Partners as a corporation, its cash available for distribution to its unitholders would be substantially
reduced. Therefore, treatment of Westlake Partners as a corporation would result in a material reduction in the
anticipated cash flow and after-tax return to its unitholders, likely causing a substantial reduction in the value of
its common units.

Westlake Partners’ partnership agreement provides that if a law is enacted or an existing law is modified or

interpreted in a manner that subjects Westlake Partners to taxation as a corporation or otherwise subjects
Westlake Partners to entity-level taxation for U.S. federal, state, local or foreign income tax purposes, the
minimum quarterly distribution amount and the target distribution amounts may be adjusted to reflect the impact
of that law or interpretation on Westlake Partners. At the state level, several states have been evaluating ways to
subject partnerships to entity-level taxation through the imposition of state income, franchise or other forms of
taxation. Westlake Partners currently owns assets and conducts business in several states, most of which impose
entity-level franchise or gross receipt taxes on partnerships. Imposition of similar entity-level taxes on Westlake
Partners in other jurisdictions in which Westlake Partners conducts operations in the future could substantially
reduce its cash available for distribution.

Risks Related to the Ownership of Our Securities

We will be controlled by our principal stockholder and its affiliates as long as they own a majority of our
common stock, and our other stockholders will be unable to affect the outcome of stockholder voting during
that time. Our interests may conflict with those of the principal stockholder and its affiliates, and we may not
be able to resolve these conflicts on terms possible in arms-length transactions.

As long as TTWF LP (the “principal stockholder”) and its affiliates (the “principal stockholder affiliates”)
own a majority of our outstanding common stock, they will be able to exert significant control over us, and our
other stockholders, by themselves, will not be able to affect the outcome of any stockholder vote. As a result, the
principal stockholder, subject to any fiduciary duty owed to our minority stockholders under Delaware law, will
be able to control all matters affecting us (some of which may present conflicts of interest), including:

(cid:129)

(cid:129)

(cid:129)

(cid:129)

the composition of our Board of Directors and, through the Board, any determination with respect to
our business direction and policies, including the appointment and removal of officers and the
determination of compensation;

any determinations with respect to mergers or other business combinations or the acquisition or
disposition of assets;

our financing decisions, capital raising activities and the payment of dividends; and

amendments to our amended and restated certificate of incorporation or amended and restated
bylaws.

The principal stockholder will be permitted to transfer a controlling interest in us without being required to

offer our other stockholders the ability to participate or realize a premium for their shares of common stock. A
sale of a controlling interest to a third party may adversely affect the market price of our common stock and our
business and results of operations because the change in control may result in a change of management decisions
and business policy. Because we have elected not to be subject to Section 203 of the General Corporation Law of
the State of Delaware, the principal stockholder may find it easier to sell its controlling interest to a third party
than if we had not so elected.

In addition to any conflicts of interest that arise in the foregoing areas, our interests may conflict with those

of the principal stockholder affiliates in a number of other areas, including:

(cid:129)

(cid:129)

(cid:129)

business opportunities that may be presented to the principal stockholder affiliates and to our officers
and directors associated with the principal stockholder affiliates, and competition between the
principal stockholder affiliates and us within the same lines of business;

the solicitation and hiring of employees from each other; and

agreements with the principal stockholder affiliates relating to corporate services that may be
material to our business.

We may not be able to resolve any potential conflicts with the principal stockholder affiliates, and even if
we do, the resolution may be less favorable than if we were dealing with an unaffiliated party, particularly if the
conflicts are resolved while we are controlled by the principal stockholder affiliates. Our amended and restated
certificate of incorporation provides that the principal stockholder affiliates have no duty to refrain from
engaging in activities or lines of business similar to ours and that the principal stockholder affiliates will not be
liable to us or our stockholders for failing to present specified corporate opportunities to us.

31

Public and investor sentiment towards climate change and other environmental, social and governance
(“ESG”) matters could adversely affect our cost of capital and the price of our common stock.

There have been intensifying efforts within the investment community (including investment advisors,
investment fund managers, sovereign wealth funds, public pension funds, universities and individual investors) to
promote the divestment of, or limit investment in, the stock of companies in the petrochemical industry. There
has also been pressure on lenders and other financial services companies to limit or curtail financing of
companies in the industry. Because we operate within the petrochemical industry, if these efforts continue or
expand, our stock price and our ability to raise capital may be negatively impacted.

Members of the investment community are increasing their focus on ESG practices and disclosures by
public companies, including practices and disclosures related to climate change and sustainability, DEI initiatives
and heightened governance standards. As a result, we may continue to face increasing pressure regarding our
ESG disclosures and practices. Additionally, members of the investment community may screen companies such
as ours for ESG disclosures and performance before investing in our stock. Over the past few years, there has
also been an acceleration in investor demand for ESG investing opportunities, and many large institutional
investors have committed to increasing the percentage of their portfolios that are allocated towards ESG
investments. With respect to any of these investors, our ESG 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
ESG 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 stock price may be
negatively impacted.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

We are a vertically integrated global manufacturer and marketer of performance and essential materials and

housing and infrastructure products. We have historically operated in two principal operating segments, Vinyls
and Olefins. As a result of recent acquisitions, we reorganized our business into two principal operating
segments, Performance and Essentials Materials and Housing and Infrastructure Products in the fourth quarter of
2021. Performance and Essential Materials segment includes Westlake North American Vinyls, Westlake North
American Chlor-alkali & Derivatives, Westlake European & Asian Chlorovinyls, Westlake Olefins and Westlake
Polyethylene. Housing and Infrastructure Products segment includes Westlake Royal Building Products,
Westlake Pipe & Fittings, Westlake Global Compounds and Westlake Dimex. The change has been
retrospectively reflected in the periods presented in this Form 10-K. We are highly integrated along our materials
chain with significant downstream integration from ethylene and chlor-alkali (chlorine and caustic soda) into
vinyls, polyethylene and styrene monomer. We also have substantial downstream integration from PVC into our
building products, PVC pipes and fittings and PVC compounds in our Housing and Infrastructure Products
segment.

Performance and Essentials Materials

Ethane-based ethylene producers have experienced a cost advantage over naphtha-based ethylene

producers during periods of higher crude oil prices. This cost advantage has resulted in a strong export market for
polyethylene and other ethylene derivatives and has benefited operating margins and cash flows for our
Performance and Essential Materials segment during such periods. However, we have seen a significant
reduction in the cost advantage enjoyed by North American ethane-based ethylene producers during periods of
lower crude oil prices. In the past year, we have seen volatility in ethane and ethylene prices, primarily due to
changes in demand resulting from the COVID-19 pandemic, anticipated timing for certain new ethylene capacity
additions and availability of natural gas liquids. Additionally, we have seen volatility in ethane and ethylene
prices in 2021 due to winter storm Uri and Hurricane Ida that resulted in shutdowns of many industry production
facilities on the Gulf Coast and delayed or extended the timing of planned turnarounds of various ethylene
crackers.

Our performance and essential materials such as ethylene, PVC, polyethylene and chlor-alkali are some of
the most widely used materials in the world and are upgraded into a wide variety of higher value-added products
used in many end-markets. Our performance and essential materials are used by customers in food and specialty
packaging; industrial and consumer packaging; medical health applications; PVC pipe applications; consumer
durables; mobility and transportation; and infrastructure products. Chlor-alkali and petrochemicals are typically
manufactured in large volume by a number of different producers using widely available technologies. The chlor-
alkali and petrochemical industries exhibit cyclical commodity characteristics, and margins are influenced by
changes in the balance between supply and demand and the resulting operating rates, the level of general
economic activity and the price of raw materials. Due to the significant size of new plants, capacity additions are
built in large increments and typically require several years of demand growth to be absorbed. The cycle is
generally characterized by periods of tight supply, leading to high operating rates and margins, followed by a
decline in operating rates and margins primarily as a result of excess new capacity additions.

Westlake is the second-largest chlor-alkali producer and the second-largest PVC producer in the world.

Demand for our products in the first half of 2020 was negatively impacted by the onset of the COVID-19
pandemic. Global demand for most of our products started strengthening in the second half of 2020 and remained
strong throughout 2021, and we expect global demand for most of our products to remain robust in 2022.

38

Depending on the performance of the global economy, potential changes in international trade and tariffs
policies, the trend of crude oil prices, the timing of the new capacity additions in North America, Asia and the
Middle East in 2022 and beyond, and the sustainability of the current, strong demand for most of our products,
our financial condition, results of operations or cash flows could be negatively or positively impacted.

We purchase significant amounts of ethane feedstock, natural gas, ethylene and salt from external suppliers
for use in production of performance and essential materials. We also purchase significant amounts of electricity
to supply the energy required in our production processes. While we have agreements providing for the supply of
ethane feedstock, natural gas, ethylene, salt and electricity, the contractual prices for these raw materials and
energy vary with market conditions and may be highly volatile. Factors that have caused volatility in our raw
material prices in the past, and which may do so in the future include:

(cid:129)

(cid:129)

(cid:129)

(cid:129)

(cid:129)

(cid:129)

(cid:129)

the availability of feedstock from shale gas and oil drilling;

supply and demand for crude oil;

shortages of raw materials due to increasing demand;

ethane and liquefied natural gas exports;

capacity constraints due to higher construction costs for investments, construction delays, strike
action or involuntary shutdowns;

the general level of business and economic activity; and

the direct or indirect effect of governmental regulation.

Significant volatility in raw material costs tends to put pressure on product margins as sales price increases
could lag behind raw material cost increases. Conversely, when raw material costs decrease, customers may seek
immediate relief in the form of lower sales prices. We currently use derivative instruments to reduce price
volatility risk on feedstock commodities and lower overall costs. Normally, there is a pricing relationship
between a commodity that we process and the feedstock from which it is derived. When this pricing relationship
deviates from historical norms, we have from time to time entered into derivative instruments and physical
positions in an attempt to take advantage of this relationship.

Our historical results have been significantly affected by our plant production capacity, our efficient use of

that capacity and our ability to increase capacity. Since our inception, we have followed a disciplined growth
strategy that focuses on plant acquisitions, new plant construction and internal expansion. We evaluate each
expansion project on the basis of its ability to produce sustained returns in excess of our cost of capital and its
ability to improve efficiency or reduce operating costs. We also regularly look at acquisition opportunities that
would be consistent with, or complimentary to, our overall business strategies. Depending on the size of the
acquisition, any such acquisitions could require external financing.

As noted above in Item 1A, “Risk Factors,” we are subject to extensive environmental regulations, which
may impose significant additional costs on our operations in the future. Further, concerns about GHG emissions
and their possible effects on climate change has led to the enactment of regulations, and to proposed legislation
and additional regulations, that could affect us in the form of increased cost of feedstocks and fuel, other
increased costs of production and decreased demand for our products. While we do not expect any of these
enactments or proposals to have a material adverse effect on us in the near term, we cannot predict the longer-
term effect of any of these regulations or proposals on our future financial condition, results of operations or cash
flows.

39

Housing and Infrastructure Products

Our Housing and Infrastructure Products segment is primarily comprised of building products, PVC pipes
and fittings and PVC compound products. Our sales are affected by the individual decisions of distributors and
dealers on the levels of inventory they carry, their views on product demand, their financial condition and the
manner in which they choose to manage inventory risk. A significant portion of our performance in this segment
is driven by the activities in the residential construction and repair and remodeling markets in North America.
Performance of our housing and infrastructure products businesses over time are generally reflective of the trends
of building permits and housing starts in the New Residential Construction Survey by the U.S. Census Bureau
and Repair and Remodeling Index (RRI) provided by the National Association of Home Builders (“NAHB”)
among others. Looking ahead, we expect that the approval of the Infrastructure Investment and Jobs Act in
November 2021 will have a favorable impact on certain industries related to our Housing and Infrastructure
Products segment in the future.

The following table presents annual historical housing starts per the U.S. Census Bureau and the 2022

outlook per the NAHB:

North American PVC facilities within the Performance and Essential Materials segment supply most of the

PVC required for our building products and PVC pipes and fittings plants. Our raw materials for stone, roofing
and accessories, windows, shutters and specialty tool products are externally purchased. PVC required for the
PVC compounds plants is either internally sourced from our North American and Asian facilities within the
Performance and Essential Materials segment or externally purchased based on the location of the plants. The
remaining feedstocks required, including pigments, fillers, stabilizers and other ingredients, are purchased under
short-term contracts based on prevailing market prices.

Factors that have caused volatility in our raw material prices and production processes in the past, and
which may do so in the future include significant fluctuation in prices of these raw materials in response to,
among other things, variable worldwide supply and demand across different industries, speculation in
commodities futures, general economic or environmental conditions, labor costs, competition, import duties,
tariffs, worldwide currency fluctuations, freight, regulatory costs, and product and process evolutions that impact
demand for the same materials. Increasing raw material prices directly impact our cost of sales and our ability to
maintain margins depends on implementing price increases in response to increasing raw material costs. The
market for our products may or may not accept price increases, and as such, our future financial condition, results
of operations or cash flows could be materially impacted.

Non-GAAP Financial Measures

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 SEC as one that purports

40

to measure 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. In this report, we disclose non-GAAP financial measures, primarily
earnings before interest, taxes, depreciation and amortization (“EBITDA”). We define EBITDA as net income
before interest expense, income taxes, depreciation and amortization. The non-GAAP financial measures
described in this Form 10-K are not substitutes for the GAAP measures of earnings and cash flows.

EBITDA is included in this Form 10-K because our management considers it an important supplemental

measure of our performance and believes that it is frequently used by securities analysts, investors and other
interested parties in the evaluation of companies in our industry, some of which present EBITDA when reporting
their results. We regularly evaluate our performance as compared to other companies in our industry that have
different financing and capital structures and/or tax rates by using EBITDA. In addition, we utilize EBITDA in
evaluating acquisition targets. Management also believes that EBITDA is a useful tool for measuring our ability
to meet our future debt service, capital expenditures and working capital requirements, and EBITDA is
commonly used by us and our investors to measure our ability to service indebtedness. EBITDA is not a
substitute for the GAAP measures of net income, income from operations and net cash provided by operating
activities and is not necessarily a measure of our ability to fund our cash needs. 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 EBITDA are
included in the “Results of Operations” section below.

Significant Developments

COVID-19, Industry Conditions and Our Business

On March 11, 2020, the World Health Organization declared the ongoing COVID-19 outbreak a pandemic

and recommended containment and mitigation measures worldwide. The pandemic has resulted in widespread
adverse impacts on the global economy. We experienced significant disruptions in the second quarter of 2020 as
the pandemic and its impact on the global economy spread through most of our markets. We were designated as
an essential industry by many governments based on the nature of the products we manufacture. While demand
for some of our products used in cleaning, packaging and medical applications and manufacturing continued to
be firm, we expected lower demand for certain of our other products that led us to proactively temporarily idle
production at several of our smaller non-integrated plants and reduce operating rates at others in the beginning of
the second quarter of 2020. Since the middle of the second quarter of 2020, a general ease in government
restrictions in many jurisdictions across the world has resulted in a gradual increase in demand for our products.
As a result, all of our idled plants recommenced production. Except for the impact of the winter storm Uri and
Hurricane Ida, operating rates have improved for most of our plants since the second half of 2020 due to
continuing increase in demand for our products. Though the government restrictions across the world generally
eased through the fourth quarter of 2021, there is considerable uncertainty regarding the extent to which
COVID-19 will continue to spread and the extent and duration of governmental and other measures implemented
to try to slow the spread of the virus. Factors that could impact the spread of COVID-19 include timing and
logistics with respect to the distribution of vaccines globally, the efficacy of the available vaccines (including
with respect to the more recent variants of COVID-19), vaccine hesitancy and the availability of other treatments.

41

We continue to monitor the volatile environment and may reduce operating rates or idle production if the
pandemic and its financial impacts persist or worsen. Considering the uncertain and volatile environment, we
could continue to experience significant disruptions to our business operations in the near future.

Acquisitions

Resources—Debt” below and Note 11 to the consolidated financial statements included in this Form 10-K for
more information.

Hurricane Ida

On August 29, 2021, Hurricane Ida made a landfall in Louisiana as a category 4 storm. Due to Hurricane
Ida, several of our facilities in the region experienced disruption to their operations, resulting in lost production
and sales and higher maintenance expense. Our facilities impacted by Hurricane Ida have resumed production.

Petro 2 Facility Flash Fire

In September 2021, OpCo’s Petro 2 ethylene unit commenced turnaround activities. On September 27,

2021, shortly after the turnaround commenced, there was a flash fire at the quench tower of the Petro 2 facility.
Several contractors working on the quench tower were injured. Although there was no sustained fire or offsite
impact resulting from the incident and the quench tower did not sustain significant damage, due to the subsequent
investigation by the Occupational Safety and Health Administration, the duration of the turnaround was extended
and concluded in December 2021. There are lawsuits pending in connection with the flash fire at the quench
tower.

2021 Compared with 2020

Summary

For the year ended December 31, 2021, net income attributable to Westlake Corporation was

$2,015 million, or $15.58 per diluted share, on net sales of $11,778 million. This represents an increase in net
income attributable to Westlake Corporation of $1,685 million, or $13.02 per diluted share, compared to 2020 net
income attributable to Westlake Corporation of $330 million, or $2.56 per diluted share, on net sales of

46

$7,504 million. Income from operations was $2,800 million for the year ended December 31, 2021 as compared
to $429 million for the year ended December 31, 2020, an increase of $2,371 million. The increase in net income
and income from operations was primarily due to significantly higher global sales prices and integrated margins
for our major products due to the strengthening of demand for our products resulting from continued
improvement in global economic activity from the severe impact of the COVID-19 pandemic in 2020, strong
residential construction and repair and remodeling markets in North America and strong demand from the
packaging and other consumer markets. Net income and income from operations for the year ended
December 31, 2021 were positively impacted by higher margin contribution on ethylene produced by LACC. Net
income and income from operations for the year ended December 31, 2021 was negatively impacted by higher
feedstock costs, fuel costs and selling, general and administrative expense. The year ended December 31, 2020
net income included an income tax rate benefit of $95 million resulting from the carryback of federal net
operating losses permitted by the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). Net
sales increased by $4,274 million to $11,778 million in 2021 from $7,504 million in 2020, mainly due to higher
sales prices for our major products as well as higher sales volumes for Housing and Infrastructure Products due
to our acquisitions in 2021.

Net Sales. Net sales increased by $4,274 million, or 57%, to $11,778 million in 2021 from $7,504 million
in 2020, primarily attributable to higher sales prices for our major products as well as higher sales volumes for
Housing and Infrastructure Products due to our acquisitions in 2021. Average sales prices for 2021 increased by
51% as compared to 2020 due to the strong demand for our products resulting from continued improvement in
global economic activity, strong residential construction, repair and remodeling markets in North America, and
strong demand from the packaging and other consumer markets. Sales volumes increased by 6% in 2021 as
compared to 2020, primarily due to the 2021 Acquisitions.

Gross Profit. Gross profit margin percentage increased to 30% in 2021 from 14% in 2020. The increase in

gross profit margin was primarily due to higher sales prices and margins for our major products. Gross profit
margin for the year ended

December 31, 2021 was also positively impacted by the margin contributed from LACC’s produced

ethylene. Gross profit margin for the year ended December 31, 2021 was negatively impacted by higher
feedstock and fuel costs.

Selling, General and Administrative Expenses. Selling, general and administrative expenses increased by

$102 million to $551 million in 2021 from $449 million in 2020. This increase was mainly due to higher
employee compensation, selling and consulting expenses and the inclusion of expenses related to the 2021
Acquisitions.

Amortization of Intangibles. Amortization expense increased by $14 million to $123 million in 2021 from

$109 million for 2020, primarily due to the amortization of intangibles associated with the 2021 Acquisitions.

Restructuring, Transaction and Integration-related Costs. Restructuring, transaction and integration-

related costs were $21 million in 2021 as compared to $36 million in 2020. The restructuring, transaction and
integration-related costs of $21 million for the year ended December 31, 2021 primarily consisted of costs
associated with the 2021 Acquisitions. Restructuring, transaction and integration-related costs of $36 million in
the year ended December 31, 2020 was primarily related to the closure of a non-integrated PVC plant located in
Germany and included the $8 million write-off of certain assets and other expenses associated with the plant
closure.

47

Interest Expense. Interest expense increased by $34 million to $176 million in 2021 from $142 million in

2020, primarily as a result of higher average debt outstanding in 2021 as compared to the year ended
December 31, 2020 and the settlement of interest rate lock arrangements associated with the issuance of the
Notes. See “Liquidity and Capital Resources—Debt” below and Note 11 to the consolidated financial statements
included in this Form 10-K for further discussion of our indebtedness.

Other Income, Net. Other income, net of $53 million in 2021 was higher as compared to other income, net

of $44 million in 2020. This increase was primarily due to higher expected return on pension plan assets.

Income Taxes. The effective income tax rate was an expense of 23% in 2021 as compared to a benefit of

13% in 2020. The change in effective tax rate in 2021 as compared to 2020 was primarily due to the income tax
rate benefit in the year ended December 31, 2020 resulting from the carryback of federal net operating loss to
taxable years that were taxed at the U.S. corporate tax rate of 35% as permitted under the CARES Act, partially
offset by the reduction in the Section 199 domestic manufacturing deduction as a result of the net operating loss
carryback.

Performance and Essential Materials Segment

Net Sales. Net sales for the Performance and Essential Materials segment increased by $3,205 million, or

59%, to $8,670 million in 2021 from $5,465 million in 2020. Average sales prices for the Performance and
Essential Materials segment increased by 58% in 2021 as compared to 2020. The higher performance materials
sales prices were due to higher polyethylene and PVC resin sales prices. The higher essential materials sales
prices were primarily driven by the higher prices for caustic due to improved global economic activity. Sales
volumes for the Performance and Essential Materials segment remained relatively consistent in 2021 as
compared to 2020.

Income from Operations. Income from operations for the Performance and Essential Materials segment

increased by $2,318 million to $2,549 million in 2021 from $231 million in 2020. This increase in income from
operations was primarily due to higher sales prices and margins for polyethylene, PVC resin and caustic soda,
mainly resulting from the continued improvement in global economic activity from the severe impact of the
COVID-19 pandemic in 2020. The increase in income from operations as compared to the prior year was
negatively impacted by higher feedstock and fuel costs. Income from operations for the year ended December 31,
2021 was also impacted by Winter Storm Uri and Hurricane Ida, while income from operations for the year
ended December 31, 2020 was negatively impacted by the onset of the COVID-19 pandemic and Hurricanes
Laura and Delta.

Housing and Infrastructure Products Segment

Net Sales. Net sales for the Housing and Infrastructure Products segment increased by $1,069 million, or
52%, to $3,108 million in 2021 from $2,039 million in 2020. In addition to the net sales from the businesses we
acquired in the second half of 2021, the increase in net sales was also driven by higher sales prices for our major
products in the housing and infrastructure businesses. Average sales prices increased by 33% from 2020 to due to
strong demand for our major products in the residential construction and repair and remodeling markets. Sales
volumes for the Housing and Infrastructure Products segment increased by 19% in 2021 as compared to 2020 due
to strong demand as well as the businesses we acquired in the second half of 2021.

Income from Operations. Income from operations for the Housing and Infrastructure Products segment

increased by $100 million to $356 million in 2021 from $256 million in 2020. The increase in income from

48

operations was primarily due to significantly higher sales prices and margins driven by robust housing
construction and remodeling activity resulting from the continued economic recovery from the COVID-19
pandemic. Additionally, 2021 experienced higher energy costs as well as the impacts from Winter Storm Uri and
Hurricane Ida, while income from operations for the year ended December 31, 2020 was negatively impacted by
the onset of the COVID-19 pandemic and Hurricanes Laura and Delta.

2020 Compared with 2019

Summary

For the year ended December 31, 2020, net income attributable to Westlake Corporation was $330 million,
or $2.56 per diluted share, on net sales of $7,504 million. This represents a decrease in net income attributable to
Westlake Corporation of $91 million, or $0.69 per diluted share, compared to 2019 net income attributable to
Westlake Corporation of $421 million, or $3.25 per diluted share, on net sales of $8,118 million. Net income for
the year ended December 31, 2020 decreased as compared to the prior year primarily due to lower global sales
prices for several of our major products, including caustic soda, and lower sales volumes for caustic soda
resulting from the impact of the COVID-19 pandemic and lower crude oil prices. Net income for 2020 was also
impacted by the shutdowns of our Lake Charles facilities in the second half of 2020 due to Hurricanes Laura and
Delta, which resulted in lower plant operating rates, higher maintenance expense and lower production for many
of our major products. In addition, in 2020 we had a higher interest expense related to higher average
borrowings. These decreases were partially offset by the income tax rate benefit of $95 million, or $0.74 per
diluted share, resulting from the carryback of federal net operating losses permitted by the CARES Act, higher
sales volumes for housing and infrastructure products, higher contributions from our ethylene joint venture
LACC, LLC (“LACC”) and lower fuel costs and selling, general and administrative expenses. Income from
operations was $429 million for the year ended December 31, 2020 as compared to $656 million for the year
ended December 31, 2019, a decrease of $227 million. The decrease in income from operations was primarily
due to lower global sales prices for our major products, lower sales volume for caustic soda, lower operating
rates and higher maintenance expense due to Hurricanes Laura and Delta. The decreases were partially offset by
higher sales volumes for housing and infrastructure products and higher contributions from LACC, lower fuel
costs and selling, general and administrative costs. Net sales decreased by $614 million to $7,504 million in 2020
from $8,118 million in 2019, mainly due to lower sales prices and volumes for several of our major products,
including caustic soda, partially offset by higher sales volumes for housing and infrastructure products in the
second half of the year ended December 31, 2020.

Net Sales. Net sales decreased by $614 million, or 8%, to $7,504 million in 2020 from $8,118 million in
2019, primarily attributable to lower sales prices and volumes for several of our major products, including caustic
soda, partially offset by higher sales volumes for housing and infrastructure products. Average sales prices for
2020 decreased by 4% as compared to 2019 due to slower global economic activity as a result of the COVID-19
pandemic and lower crude oil prices. Sales volumes decreased by 3% in 2020 as compared to 2019.

Gross Profit. Gross profit margin percentage decreased to 14% in 2020 from 16% in 2019. The gross profit

margin decreased primarily due to lower global sales prices for several of our major products and lower sales
volumes for caustic soda resulting from the impact of the COVID-19 pandemic and lower crude oil prices. Gross
profit margin was also impacted by the shutdown of our Lake Charles facilities in the second half of 2020 due to
Hurricanes Laura and Delta, which resulted in lower plant operating rates, higher maintenance expense and lower
production for many of our major products. These decreases were partially offset by higher sales volumes for
housing and infrastructure products and lower fuel costs.

49

Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased by
$9 million to $449 million in 2020 from $458 million in 2019. This decrease was mainly due to lower employee
compensation and selling expenses.

Amortization of Intangibles. Amortization expense for 2020 was $109 million, which was comparable to

$109 million for 2019.

Restructuring, Transaction and Integration-related Costs. Restructuring, transaction and integration-

related costs were $36 million in 2020 as compared to $37 million in 2019. The restructuring, transaction and
integration-related costs for 2020 primarily related to the closure of a non-integrated PVC plant located in
Germany and included the $8 million write-off of certain assets and other expenses associated with the plant
closure. The restructuring, transaction and integration-related costs for 2019 primarily consisted of restructuring
expenses of $26 million and acquisition costs.

Interest Expense. Interest expense increased by $18 million to $142 million in 2020 from $124 million in
2019, primarily as a result of higher average debt outstanding in 2020 as compared to 2019. The higher average
debt balance in 2020 was primarily due to the borrowing of $1 billion under our revolving credit facility in
March 2020 out of an abundance of caution (which we fully repaid in June 2020), the issuance of the
€700 million aggregate principal amount of 1.625% 2029 Senior Notes in July 2019, which were outstanding for
the full calendar year in 2020 (as compared to less than half a year in 2019), and the issuance of the $300 million
aggregate principal amount of 3.375% 2030 Senior Notes in June 2020 and lower interest capitalization due to
lower activity with respect to capital expenditure projects during 2020 as compared to the prior year, partially
offset by the purchase in lieu of redemption of the 6 1⁄ 2% 2029 GO Zone Bonds, the 6 1⁄ 2% 2035 GO Zone
Bonds and the 6 1⁄ 2% 2035 IKE Zone Bonds. See “Liquidity and Capital Resources—Debt” below and Note 11
to the consolidated financial statements included in this Form 10-K for further discussion of our indebtedness.

Other Income, Net. Other income, net of $44 million in 2020 was higher as compared to other income, net

of $38 million in 2019. This increase was primarily due to higher expected return on pension plan assets.

Income Taxes. The effective income tax rate was a benefit of 13% in 2020 as compared to an expense of

19% in 2019. The change in effective tax rate in 2020 as compared to the prior year was primarily due to the
income tax rate benefit resulting from the carryback of federal net operating loss to taxable years that were taxed
at the U.S. corporate tax rate of 35% as permitted under the CARES Act, partially offset by the reduction in the
Section 199 domestic manufacturing deduction as a result of the net operating loss carryback.

Performance and Essential Materials Segment

Net Sales. Net sales for the Performance and Essential Materials segment decreased by $719 million, or

12%, to $5,465 million in 2020 from $6,184 million in 2019. Average sales prices for the Performance and
Essential Materials segment decreased by 6% in 2020, as compared to 2019. The lower performance materials
sales prices were due to lower polyethylene prices as a result of increased production from new industry capacity
and lower PVC resin sales prices due to slower global economic activity as a result of the COVID-19 pandemic.
The lower essential materials sales prices were driven by lower caustic soda prices. Average sales volumes
decreased by 6% in 2020 as compared to 2019 due to the slower global economic activity as a result of the
COVID-19 pandemic. Lower performance materials global sales volumes were due to lower polyethylene and
PVC resin sales volumes and lower essential materials sales volumes were driven by lower caustic soda sales
volume.

50

Income from Operations. Income from operations for the Performance and Essential Materials segment
decreased by $338 million to $231 million in 2020 from $569 million in 2019. This decrease in income from
operations was primarily due to lower caustic soda and PVC resin sales prices and lower PVC resin and
polyethylene sales volumes, partially offset by lower purchased ethylene, ethane feedstock and fuel costs.
Trading activity in 2020 resulted in a gain of approximately $4 million as compared to a loss of $26 million in
2019.

Housing and Infrastructure Products Segment

Net Sales. Net sales for the Housing and Infrastructure Products segment increased by $105 million, or 5%,

to $2,039 million in 2020 from $1,934 million in 2019. Sales volumes for the Housing and Infrastructure
Products segment increased by 5% in 2020 as compared to 2019, primarily due to higher demand for our major
products in the residential construction and repair and remodeling markets, partially offset by lower
infrastructure products sales due to the impact of the COVID-19 pandemic.

Income from Operations. Income from operations for the Housing and Infrastructure Products segment

increased by $120 million to $256 million in 2020 from $136 million in 2019. The increase in income from
operations was primarily due to higher sales volumes and prices for our major housing products and lower
feedstock costs partially offset by lower sales for infrastructure products. The income from operations for the
year ended December 31, 2020 was also negatively impacted by the onset of the COVID-19 pandemic and
Hurricanes Laura and Delta.

Cash Flows

Operating Activities

Operating activities provided cash of $2,394 million in 2021, as compared to cash provided by operating

activities of $1,297 million in 2020. The $1,097 million increase in cash flows from operating activities was
mainly due to the increase in income from operations, which was partially offset by working capital changes and
an unfavorable change related to the turnaround at OpCo’s Petro 2 facility and other turnaround activities.
Changes in components of working capital, which we define for purposes of this cash flow discussion as
accounts receivable, inventories, prepaid expenses and other current assets, less accounts payable and accrued
and other liabilities, used cash of $383 million in 2021, as compared to $17 million of cash used in 2020, an
unfavorable change of $366 million. The majority of the unfavorable changes in 2021 were driven by higher
accounts receivable and higher inventories, partially offset by higher accounts payable and accrued and other
liabilities. The unfavorable change in accounts receivable was primarily driven by higher sales prices resulting in
higher trade customer balances. The higher inventories, accounts payable and accrued and other liabilities in
2021 were primarily driven by higher inventory cost and an increase in operating activities, as compared to 2020.

Operating activities provided cash of $1,297 million in 2020 as compared to cash provided by operating

activities of $1,301 million in 2019. The changes in cash flows from operating activities in 2020, as compared to
2019, were mainly driven by the decrease in income from operations, the income tax refund of $188 million
under the CARES Act and working capital changes. Changes in components of working capital, which we define
for purposes of this cash flow discussion as accounts receivable, inventories, prepaid expenses and other current
assets, less accounts payable and accrued and other liabilities used cash of $17 million in 2020, as compared to
$68 million of cash provided in 2019, an unfavorable change of $85 million. Unfavorable changes in working
capital were due to a change in accounts receivable, which was driven by higher sales in the fourth quarter of
2020 and the expected additional income tax refund resulting from the CARES Act, as discussed previously.

51

Favorable changes in working capital were due to lower inventories and higher accounts payable and accrued
liabilities, primarily driven by the changes in inventory levels and operating activities.

Investing Activities

Net cash used for investing activities during 2021 was $3,213 million as compared to net cash used of
$509 million in 2020. The increase in investing activities in 2021 was primarily due to the acquisitions of Boral,
LASCO and Dimex for $2,554 million in the aggregate, net of cash acquired. Capital expenditures were
$658 million in 2021 compared to $525 million in 2020. The higher capital expenditures in 2021 were primarily
associated with the turnaround at OpCo’s Petro 2 facility. Capital expenditures in 2021 and 2020 were primarily
related to projects to improve production capacity or reduce costs, maintenance and safety projects and
environmental projects at our various facilities. During 2021, we contributed $22 million to LACC and
$2 million to an unconsolidated investee compared to a net return of investment of $40 million from LACC in
2020.

Net cash used for investing activities during 2020 was $509 million as compared to net cash used of
$1,954 million in 2019. Capital expenditures were $525 million in 2020 compared to $787 million in 2019. The
decrease in capital expenditures was primarily due to fewer expansion projects in 2020, as compared to 2019.
Capital expenditures in 2020 were primarily related to projects to improve production capacity or reduce costs,
maintenance and safety projects and environmental projects at our various facilities. In 2020, we received
$44 million from our joint venture, LACC, representing a return of investment and we contributed $4 million.
The Company’s contribution to unconsolidated subsidiaries in 2020 was primarily comprised of $14 million
towards our investment in RS Cogen. Investing activities in 2019 were primarily due to acquisitions for
$314 million, net of cash acquired, the purchase of the additional 34.8% interest in LACC for $817 million in
November 2019 and payment of $45 million to fund the construction costs of LACC. Capital expenditures in
2019 included certain announced expansion projects as well as projects to improve production capacity or reduce
costs, maintenance and safety and environmental projects at our various facilities.

Financing Activities

Net cash provided by financing activities during 2021 was $1,437 million as compared to net cash used of

$216 million in 2020. The activities during 2021 were primarily related to the registered public offering of
$300 million aggregate principal amount of the 0.875% 2024 Senior Notes, $350 million aggregate principal
amount of the 2.875% 2041 Senior Notes, $600 million aggregate principal amount of the 3.125% 2051 Senior
Notes and $450 million aggregate principal amount of the 3.375% 2061 Senior Notes and the payment of debt
issuance costs of $18 million related to the Notes. The remaining activities in 2021 were primarily related to the
$145 million payment of cash dividends, the $48 million payment of cash distributions to noncontrolling interests
and repurchases of our common stock for an aggregate purchase price of $30 million.

Net cash used for financing activities during 2020 was $216 million as compared to net cash provided of

$630 million in 2019. In 2020, out of abundance of caution, we borrowed $1,000 million under our revolving
credit facility, which we subsequently fully repaid in June 2020. In 2020, we completed the registered public
offering of $300 million aggregate principal amount of the 3.375% 2030 Senior Notes and we purchased in lieu
of optional redemption the $100 million 6 1⁄ 2% 2029 GO Zone Senior Notes, the $89 million 6 1⁄ 2% 2035 GO
Zone Senior Notes and the $65 million 6 1⁄ 2% 2035 IKE Zone Senior Notes. The remaining activities in 2020
were primarily related to the $137 million payment of cash dividends, the $55 million payment of cash
distributions to noncontrolling interests, repurchases of common stock of $54 million and repayment of short-

52

term notes payable of $17 million. In 2019, we received proceeds of $784 million from the issuance of the
1.625% 2029 Senior Notes and $63 million from the issuance of Westlake Partners common units. The
remaining activities in 2019 were primarily related to the $132 million payment of cash dividends, the
$50 million payment of cash distributions to noncontrolling interests and repurchases of common stock for an
aggregate purchase price of $30 million.

Liquidity and Capital Resources

Liquidity and Financing Arrangements

Our principal sources of liquidity are from cash and cash equivalents, cash from operations, short-term

borrowings under the Credit Agreement and our long-term financing.

In November 2014, our Board of Directors authorized a $250 million stock repurchase program (the “2014

Program”). In November 2015, our Board of Directors approved the expansion of the 2014 Program by an
additional $150 million. In August 2018, our Board of Directors approved the further expansion of the existing
2014 Program by an additional $150 million. As of December 31, 2021, we had repurchased 7,431,520 shares of
our common stock for an aggregate purchase price of approximately $449 million under the 2014 Program.
During the year ended December 31, 2021, 355,800 shares of our common stock were repurchased for an
aggregate purchase price of $30 million under the 2014 Program. Purchases under the 2014 Program may be
made either through the open market or in privately negotiated transactions. Decisions regarding the amount and
the timing of purchases under the 2014 Program will be influenced by our cash on hand, our cash flow from
operations, general market conditions and other factors. The 2014 Program may be discontinued by our Board of
Directors at any time.

On October 4, 2018, Westlake Partners and Westlake Partners GP, the general partner of Westlake
Partners, entered into an Equity Distribution Agreement with UBS Securities LLC, Barclays Capital Inc.,
Citigroup Global Markets Inc., Deutsche Bank Securities Inc., RBC Capital Markets, LLC, Merrill Lynch,
Pierce, Fenner & Smith Incorporated and Wells Fargo Securities, LLC to offer and sell Westlake Partners
common units, from time to time, up to an aggregate offering amount of $50 million. This Equity Distribution
Agreement was amended on February 28, 2020 to reference a new shelf registration for utilization under this
agreement. No common units have been issued under this program in 2019, 2020 or 2021.

We believe that our sources of liquidity as described above are adequate to fund our normal operations and

ongoing capital expenditures. Funding of any potential large expansions such as our recent Acquisitions or
potential future acquisitions or the repayment of debt may likely necessitate, and therefore depend on our ability
to obtain, additional financing in the future. We may not be able to access additional liquidity at cost effective
interest rates due to the volatility of the commercial credit markets.

On August 19, 2021, we completed the registered public offering of the Notes. See “Liquidity and Capital

Resources—Debt” below for more information.

Cash and Cash Equivalents

As of December 31, 2021, our cash and cash equivalents totaled $1,908 million. In addition, we have the

Credit Agreement available to supplement cash if needed, as described under “Debt” below.

Debt

As of December 31, 2021, our indebtedness totaled $5,180 million. See Note 11 to the consolidated

financial statements appearing elsewhere in this Form 10-K for a discussion of our long-term indebtedness.

53

Defined terms used in this section have the definitions assigned to such terms in Note 11 to the consolidated
financial statements included in Item 8 of this Form 10-K.

Our ability to make payments on our indebtedness and to fund planned capital expenditures will depend on
our ability to generate cash in the future, which is subject to general economic, financial, competitive, legislative,
regulatory and other factors that are beyond our control. Based on our current level of operations and unless we
were to undertake a new expansion or large acquisition, we believe our cash flows from operations, available
cash and available borrowings under the Credit Agreement will be adequate to meet our normal operating needs
for the foreseeable future.

Credit Agreement

On July 24, 2018, we entered into a new $1 billion revolving credit facility that is scheduled to mature on
July 24, 2023 (the “Credit Agreement”). The Credit Agreement bears interest at either (a) LIBOR plus a spread
ranging from 1.00% to 1.75% or (b) Alternate Base Rate plus a spread ranging from 0.00% to 0.75% in each
case depending on the credit rating of the Company. As of December 31, 2021, we had no borrowings
outstanding under the Credit Agreement. As of December 31, 2021, we had no outstanding letters of credit and
had borrowing availability of $1 billion under the Credit Agreement. The Credit Agreement contains certain
affirmative and negative covenants, including a quarterly total leverage ratio financial maintenance covenant. As
of December 31, 2021, we were in compliance with the total leverage ratio financial maintenance covenant.

The Credit Agreement also contains certain events of default and if and for so long as certain events of
default have occurred and are continuing, any overdue amounts outstanding under the Credit Agreement will
accrue interest at an increased rate, the lenders can terminate their commitments thereunder and payments of any
outstanding amounts could be accelerated by the lenders. None of our subsidiaries are required to guarantee our
obligations under the Credit Agreement.

The Credit Agreement includes a $150 million sub-limit for letters of credit, and any outstanding letters of

credit will be deducted from availability under the facility. The Credit Agreement also provides for a
discretionary $50 million commitment for swingline loans to be provided on a same-day basis. We may also
increase the size of the facility, in increments of at least $25 million, up to a maximum of $500 million, subject to
certain conditions and if certain lenders agree to commit to such an increase.

3.60% Senior Notes due 2022

In July 2012, we issued $250 million aggregate principal amount of the 3.60% 2022 Senior Notes. We may
optionally redeem the 3.60% 2022 Senior Notes at any time and from time to time prior to April 15, 2022 (three
months prior to the maturity date) for 100% of the principal plus accrued interest and a discounted “make whole”
payment. On or after April 15, 2022, we may optionally redeem the 3.60% 2022 Senior Notes for 100% of the

Notes).

In August 2016, we completed the private offering of $750 million aggregate principal amount of our
3.60% 2026 Senior Notes and $700 million aggregate principal amount of our 5.0% 2046 Senior Notes. In March
2017, the Company commenced registered exchange offers to exchange the 3.60% 2026 Senior Notes and the
5.0% 2046 Senior Notes for new notes that are identical in all material respects to the 3.60% 2026 Senior Notes
and the 5.0% 2046 Senior Notes, except that the offer and issuance of the new Securities and Exchange
Commission-registered notes have been registered under the Securities Act of 1933, as amended (the “Securities
Act”). The exchange offers expired on April 24, 2017, and approximately 99.97% of the 3.60% 2026 Senior
Notes and 100% of the 5.0% 2046 Senior Notes were exchanged. The notes that were not exchanged in the
exchange offers have not been registered under the Securities Act or any state securities laws and may not be
offered or sold in the U.S. absent registration or an applicable exemption from registration requirements or a
transaction not subject to the registration requirements of the Securities Act or any state securities law.

Revenue Bonds

In December 1997, we entered into a loan agreement with a public trust established for public purposes for

the benefit of the Parish of Calcasieu, Louisiana. The public trust issued $11 million principal amount of
tax-exempt waste disposal revenue bonds in order to finance our construction of waste disposal facilities for an
ethylene plant. The waste disposal revenue bonds expire in December 2027 and are subject to redemption and
mandatory tender for purchase prior to maturity under certain conditions. Interest on the waste disposal revenue
bonds accrues at a rate determined by a remarketing agent and is payable quarterly. The interest rate on the waste
disposal revenue bonds at December 31, 2021 and 2020 was 0.14% and 0.14%, respectively.

1.625% Senior Notes due 2029

In July 2019, we completed the registered public offering of €700 million aggregate principal amount
of the 1.625% 2029 Senior Notes due July 17, 2029. The Company received approximately $779 million of net

8.73% 2022 RS Cogen Debt

In July 2000, RS Cogen, our 50%-owned joint venture, entered into a $75 million aggregate principal
amount senior credit facility institutional loan at an interest rate of 8.73%. All of the assets of RS Cogen are
pledged as collateral under its senior credit facility. Borrowings under this senior credit facility are repayable

As of December 31, 2021, we were in compliance with all of our long-term debt covenants.

Westlake Chemical Partners LP Credit Arrangements

Our subsidiary, Westlake Chemical Finance Corporation, is the lender party to a $600 million revolving
credit facility with Westlake Chemical Partners LP (“Westlake Partners”), originally entered into on April 29,
2015 and amended in August and December 2017. In addition, on March 19, 2020, Westlake Partners and
Westlake Chemical Finance Corporation entered into an amendment to the revolving credit facility, 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 revolving credit facility bear interest at LIBOR plus a spread
ranging from 2.0% to 3.0% (depending on Westlake Partners’ consolidated leverage ratio), payable quarterly.
Westlake Partners 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. As of December 31, 2021, outstanding borrowings
under the revolving credit facility totaled $377 million and bore interest at the LIBOR rate plus 2.0%.

Our subsidiary, Westlake Polymers LLC, is the administrative agent to a $600 million revolving credit

2021, outstanding borrowings under the credit facility totaled $23 million and bore interest at the LIBOR rate
plus 2.0%, which is accrued in arrears quarterly.

We consolidate Westlake Partners and OpCo for financial reporting purposes as we have a controlling
financial interest. As such, the revolving credit facilities described above between our subsidiaries and Westlake
Partners and OpCo are eliminated upon consolidation.

Pension Benefits Funding and Post-retirement Healthcare Benefits. Pension benefits funding obligations

due within the near term were $6 million while post-retirement healthcare benefit payment obligations due within
the near term were $8 million as of December 31, 2021. As of December 31, 2021, we had $77 million and
$53 million of pension benefit funding and post-retirement healthcare benefit obligations due over the long-term
period, respectively. The estimate of the timing of future payments under our defined benefit pension plans
which cover certain eligible employees in the United States and non-U.S. countries and our post-retirement
healthcare benefits to the employees of certain subsidiaries who meet certain minimum age and service
requirements involves the use of certain assumptions, including retirement ages and payout periods. See Note 14,
“Employee Benefits,” in the Notes to Consolidated Financial Statements in Item 8 for further information on our
obligations and the timing of expected future payments.

Purchase Obligations. Purchase obligations include agreements to purchase goods and services that are
enforceable and legally binding and that specify all significant terms, including a minimum quantity and price.
We are party to various obligations to purchase goods and services, including commitments to purchase various
feedstock, utilities, nitrogen, oxygen, product storage, pipeline usage and logistic support, in each case in the
ordinary course of our business, as well as various purchase commitments for our capital projects. As of
December 31, 2021, we had $1,890 million of enforceable and legally binding purchase commitments due within
the near term, and $5,220 million due over the long-term period.

Asset Retirement Obligations. As of December 31, 2021, we had an immaterial amount of asset retirement
obligations due within the near term, and $61 million due over the long-term period. Asset retirement obligations
includes the estimated costs and timing of payments to satisfy our recognized asset retirement obligations. We
recognize asset retirement obligations in the period in which the liability becomes probable and reasonably
estimable. Initially, the asset retirement obligation is recorded at fair value and capitalized as a component of the
carrying value of the long-lived asset to which the obligation relates. See Note 1, “Description of Business and
Significant Accounting Policies,” in the Notes to Consolidated Financial Statements in Item 8 for further detail of
our asset retirement obligations.

Critical Accounting Policies and Estimates

Critical accounting policies are those that are important to our financial condition and require
management’s most difficult, subjective or complex judgments. Different amounts would be reported under
different operating conditions or under alternative assumptions. We have evaluated the accounting policies used
in the preparation of the accompanying consolidated financial statements and related notes and believe those
policies are reasonable and appropriate. Our significant accounting policies are summarized in Note 1 to the
consolidated financial statements appearing elsewhere in this Form 10-K.

Critical accounting estimates are those estimates made in accordance with GAAP that involve a significant

level of estimation uncertainty and have had or are reasonably likely to have a material impact on our financial
condition or results of operation. Our more critical accounting estimates include those related to long-lived
assets, fair value estimates, accruals for long-term employee benefits, accounts receivable, income taxes and
environmental and legal obligations. Inherent in such estimates are certain key assumptions. We periodically

59

update the estimates used in the preparation of the financial statements based on our latest assessment of the
current and projected business and general economic environment. We believe the following to be our most
critical accounting estimates required for the preparation of our financial statements.

Long-Lived Assets. Key estimates related to long-lived assets include useful lives, recoverability of
carrying values and existence of any retirement obligations. Such estimates could be significantly modified. The
carrying values of long-lived assets could be impaired by significant changes or projected changes in supply and
demand fundamentals (which would have a negative impact on operating rates or margins), new technological
developments, new competitors with significant raw material or other cost advantages, adverse changes
associated with the United States and world economies, the cyclical nature of the chemical and refining
industries and uncertainties associated with governmental actions.

We evaluate long-lived assets for potential impairment indicators whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be recoverable, including when negative
conditions such as significant current or projected operating losses exist. Our judgments regarding the existence
of impairment indicators are based on legal factors, market conditions and the operational performance of our
businesses. Actual impairment losses incurred could vary significantly from amounts estimated. Long-lived
assets assessed for impairment are grouped at the lowest level for which identifiable cash flows are largely
independent of the cash flows of other assets and liabilities. Additionally, future events could cause us to
conclude that impairment indicators exist and that associated long-lived assets of our businesses are impaired.
Any resulting impairment loss could have a material adverse impact on our financial condition and results of
operations.

The estimated useful lives of long-lived assets range from one to 40 years. Depreciation and amortization

of these assets, including amortization of deferred turnaround costs, under the straight-line method over their
estimated useful lives totaled $840 million, $773 million and $713 million in 2021, 2020 and 2019, respectively.
If the useful lives of the assets were found to be shorter than originally estimated, depreciation or amortization
charges would be accelerated.

We defer the costs of planned major maintenance activities, or turnarounds, and amortize the costs over the

period until the next planned turnaround of the affected unit. Total costs deferred on turnarounds were
$215 million, $24 million and $40 million in 2021, 2020 and 2019, respectively. As of December 31, 2021,
deferred turnaround costs, net of accumulated amortization, totaled $261 million. Amortization in 2021, 2020
and 2019 of deferred turnaround costs was $56 million, $48 million and $55 million, respectively. Expensing
turnaround costs as incurred would likely result in greater variability of our quarterly operating results and would
adversely affect our financial position and results of operations.

Additional information concerning long-lived assets and related depreciation and amortization appears in

Notes 6 and 8 to the consolidated financial statements appearing elsewhere in this Form 10-K.

Fair Value Estimates. We develop estimates of fair value to allocate the purchase price paid to acquire a

business to the assets acquired and liabilities assumed in an acquisition, to assess impairment of long-lived assets,
goodwill and intangible assets and to record marketable securities and pension plan assets. We use all available
information to make these fair value determinations, including the engagement of third-party consultants. At
December 31, 2021, our recorded goodwill was $2,024 million. In addition, we record all pension plan assets and
certain marketable securities at fair value. The fair value of these items is determined by quoted market prices or
from observable market-based inputs. See Note 16 to the consolidated financial statements appearing elsewhere
in this Form 10-K for more information.

60

Business Combinations and Intangible Assets Including Goodwill. We account for business combinations

using the acquisition method of accounting, and accordingly, the assets and liabilities of the acquired business are
recorded at their fair values at the date of acquisition. The excess of the purchase price over the estimated fair
value is recorded as goodwill. Any changes in the estimated fair values of the net assets recorded for acquisitions
prior to the finalization of more detailed analysis, but not to exceed one year from the date of acquisition, will
change the amount of the purchase price allocable to goodwill. Any subsequent changes to any purchase price
allocations that are material to our consolidated financial results will be adjusted in the same period’s financial
statements, including the effect on earnings of changes in depreciation, amortization or other income effects, if
any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at
the acquisition date. All acquisition costs are expensed as incurred and in-process research and development
costs are recorded at fair value as an indefinite-lived intangible asset and assessed for impairment thereafter until
completion, at which point the asset is amortized over its expected useful life. Separately recognized transactions
associated with business combinations are generally expensed subsequent to the acquisition date. The application
of business combination accounting requires the use of significant estimates and assumptions. Our estimates of
fair value are based upon assumptions we believe to be reasonable, but which are inherently uncertain and
unpredictable. The fair value of the customer relationships acquired are estimated by management through a
discounted cash flow model using the multi-period excess earnings methodology, which involves the use of
significant estimates and assumptions related to revenue growth rates, operating margins, discount rates, and
customer attrition rates, among other items. The fair value of the technology and trade names acquired is
estimated by management through a discounted cash flow model using the relief from royalty methodology,
which involves the use of significant estimates and assumptions related to revenue growth rates, and discount
rates.

Goodwill is evaluated for impairment when events or changes in circumstances indicate the fair value of a
reporting unit with goodwill has been reduced below its carrying value, and otherwise at least annually. We have
historically operated in two principal operating segments, Vinyls and Olefins. In the fourth quarter of 2021, we
reorganized our business into two principal operating segments, Performance and Essential Materials and
Housing and Infrastructure Products. As part of the reorganization, we assessed and re-defined reporting units
effective as of the beginning of the fourth quarter of 2021, including reallocation of goodwill on a relative fair
value basis as applicable to affected reporting units. Goodwill impairment analyses were performed as of the
effective reorganization date both before and after the reorganization. We will perform our annual impairment
assessment for both the Performance and Essential Materials and Housing and Infrastructure Products reporting
units in October each year. We may elect to perform an optional qualitative assessment to determine whether a
quantitative impairment analysis is required. The qualitative assessment considers factors such as
macroeconomic conditions, industry and market considerations, cost factors related to raw materials and labor,
current and projected financial performance, changes in management or strategy, and market capitalization.
Alternatively, we may unconditionally elect to bypass the qualitative assessment and perform a quantitative
goodwill impairment assessment in any period.

We elected to perform the quantitative assessment for both of our segments’ reporting units during 2021.

The quantitative analysis compares a reporting unit’s fair value to its carrying amount to determine whether
goodwill is impaired. The fair values of the reporting units are calculated using both a discounted cash flow
methodology and a market value methodology. The discounted cash flow projections are based on a forecast to
reflect the cyclicality of the business. The forecast is based on historical results and estimates by management,
including its strategic and operational plans, and financial performance of the market. The future cash flows are
discounted to present value using an applicable discount rate. The significant assumptions used in determining

61

the fair value of the reporting unit using the market value methodology include the determination of appropriate
market comparables and the estimated multiples of EBITDA a willing buyer is likely to pay. Even if the fair
values of the reporting units decreased by 10% from the fair values determined in the most recent quantitative
tests performed during 2021, the carrying values of the reporting units would not have exceeded their fair values.
See Item 1A, “Risk Factors—If our goodwill, indefinite-lived intangible assets or other intangible assets become
impaired in the future, we may be required to record non-cash charges to earnings, which could be significant.”

The results of operations of acquired businesses are included in our consolidated financial statements from

the acquisition date.

Long-Term Employee Benefit Costs. Our costs for long-term employee benefits, particularly pension and
postretirement medical and life benefits, are incurred over long periods of time and involve many uncertainties
over those periods. The net periodic benefit cost attributable to current periods is based on several assumptions
about such future uncertainties and is sensitive to changes in those assumptions. It is our responsibility, often
with the assistance of independent experts, to select assumptions that represent the best estimates of those
uncertainties. It is also our responsibility to review those assumptions periodically and, if necessary, adjust the
assumptions to reflect changes in economic or other factors.

Accounting for employee retirement plans involves estimating the cost of benefits that are to be provided in

the future and attempting to match, for each employee, that estimated cost to the period worked. To accomplish
this, we rely extensively on advice from actuaries, and we make assumptions about inflation, investment returns,
mortality, employee turnover and discount rates that ultimately impact amounts recorded. Changes in these
assumptions may result in different expense and liability amounts. One of the more significant assumptions
relates to the discount rate for measuring benefit obligations. At December 31, 2021, the projected pension
benefit obligations for U.S. and non-U.S. plans were calculated using assumed weighted average discount rates
of 2.6% and 1.4%, respectively. The discount rates were determined using a benchmark pension discount curve
and applying spot rates from the curve to each year of expected benefit payments to determine the appropriate
discount rate. As a result of the funding relief provided by the enactment of the Bipartisan Budget Act of 2015,
no minimum funding requirements are expected during 2022 for the U.S. pension plans. Additional information
on the 2022 funding requirements and key assumptions underlying these benefit costs appear in Note 14 to the
consolidated financial statements appearing elsewhere in this Form 10-K.

The following table reflects the sensitivity of the benefit obligation of our pension plans to changes in the

actuarial assumptions:

A one-percentage point increase or decrease in assumed healthcare trend rates would not have a significant

effect on the amounts reported for the healthcare plans.

While we believe that the amounts recorded in the consolidated financial statements appearing elsewhere in

this Form 10-K related to these retirement plans are based on the best estimates and judgments available, the
actual outcomes could differ from these estimates.

62

Income Taxes. We utilize the liability method of accounting for income taxes. Under the liability method,

deferred tax assets or liabilities are recorded based upon temporary differences between the tax basis of assets
and liabilities and their carrying values for financial reporting purposes. Deferred tax expense or benefit is the
result of changes in the deferred tax assets and liabilities during the period. Valuation allowances are recorded
against deferred tax assets when it is considered more likely than not that the deferred tax assets will not be
realized. Additional information on income taxes appears in Note 17 to the consolidated financial statements
appearing elsewhere in this Form 10-K.

Environmental and Legal Obligations. We consult with various professionals to assist us in making
estimates relating to environmental costs and legal proceedings. We accrue an expense when we determine that it
is probable that a liability has been incurred and the amount is reasonably estimable. While we believe that the
amounts recorded in the accompanying consolidated financial statements related to these contingencies are based
on the best estimates and judgments available, the actual outcomes could differ from our estimates. Additional
information about certain legal proceedings and environmental matters appears in Note 22 to the consolidated
financial statements appearing elsewhere in this Form 10-K.

Asset Retirement Obligations. We recognize asset retirement obligations in the period in which the liability
becomes probable and reasonably estimable. Initially, the asset retirement obligation is recorded at fair value and
capitalized as a component of the carrying value of the long-lived asset to which the obligation relates. The
liability is recorded at its future value each period, and the capitalized cost is depreciated over the estimated
useful life of the related asset. Upon settlement of the liability, a gain or loss is recorded. We have conditional
asset retirement obligations for the removal and disposal of hazardous materials from certain of our
manufacturing facilities. Additional information on asset retirement obligations appears in Note 1, under Asset
Retirement Obligations, to the consolidated financial statements appearing elsewhere in this Form 10-K.

We also have conditional asset retirement obligations that have not been recognized because the fair values

of the conditional legal obligations cannot be measured due to the indeterminate settlement date of the
obligations. Settlements of the unrecognized conditional asset retirement obligations are not expected to have a
material adverse effect on our financial condition, results of operations or cash flows in any individual reporting
period.

Recent Accounting Pronouncements

See Note 1 to the consolidated financial statements included in Item 8 of this Form 10-K for a full
description of recent accounting pronouncements, including expected dates of adoption and estimated effects on
results of operations and financial condition.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

Commodity Price Risk

A substantial portion of our products and raw materials are commodities whose prices fluctuate as market
supply and demand fundamentals change. Accordingly, product margins and the level of our profitability tend to
fluctuate with changes in the business cycle. We try to protect against such instability through various business
strategies. Our strategies include ethylene product feedstock flexibility and moving downstream into our other
products where pricing is more stable. We use derivative instruments in certain instances to reduce price
volatility risk on feedstocks and products. Based on our open derivative positions on ethane at December 31,
2021, a hypothetical $0.10 increase in the price of a gallon of ethane would have increased our income before

63

income taxes by $17 million and a hypothetical $0.10 increase in the price of a million British thermal units of
natural gas would have decreased our income before income taxes by $1 million.

Interest Rate Risk

We are exposed to interest rate risk with respect to fixed and variable rate debt. At December 31, 2021, we

had $5,263 million aggregate principal amount of fixed rate debt. We are subject to the risk of higher interest
cost if and when this debt is refinanced. If interest rates were 1.0% higher at the time of refinancing, our annual
interest expense would increase by approximately $53 million. Also, at December 31, 2021, we had $20 million
principal amount of variable rate debt outstanding, which primarily represents the tax-exempt waste disposal
revenue bonds. We do not currently hedge our variable interest rate debt, but we may do so in the future. The
average variable interest rate for our variable rate debt of $20 million as of December 31, 2021 was 0.17%. A
hypothetical 100 basis point increase in the average interest rate on our variable rate debt would not result in a
material change in the interest expense. During June and July 2021, in order to manage the interest rate risk
associated with potential borrowings, we entered into treasury lock agreements to fix the treasury yield
component of the interest cost. These agreements settled in August 2021 on the issuance of the Notes.

LIBOR is used as a reference rate for borrowings under our revolving line of credit. The phase-out of
LIBOR commenced at the end of 2021 and is set to conclude by June 30, 2023. We do not expect the impact of
the LIBOR phase out to be material as we did not have any external LIBOR-based borrowings outstanding at
December 31, 2021.

Foreign Currency Exchange Rate Risk

We are exposed to foreign currency exchange rate risk associated with our international operations.
However, the effect of fluctuations in foreign currency exchange rates caused by our international operations has
not had a material impact on our overall operating results. We may engage in activities to mitigate our exposure
to foreign currency exchange risk in certain instances through the use of currency exchange derivative
instruments, including forward exchange contracts, cross-currency swaps or spot purchases. A forward exchange
contract obligates us to exchange predetermined amounts of specified currencies at a stated exchange rate on a
stated date. A cross-currency swap obligates us to make periodic payments in the local currency and receive
periodic payments in our functional currency based on the notional amount of the instrument. In January 2018,
we entered into foreign exchange hedging contracts designated as net investment hedges with an aggregate
notional value of €220 million designed to reduce the volatility in stockholders’ equity from changes in currency
exchange rates associated with our net investments in foreign operations. In July 2019, we terminated a portion
of the foreign exchange hedging contract with a notional value of €70 million. The notional value of the
remaining net investment hedges was €150 million at December 31, 2021. The arrangement is scheduled to settle
in 2026.

In July 2019, we completed the registered public offering of €700 million aggregate principal amount
of the 1.625% 2029 Senior Notes. We designated this euro-denominated debt as a non-derivative net investment
hedge of a portion of our net investments in euro functional-currency denominated subsidiaries to offset foreign
currency fluctuations.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Westlake Corporation is responsible for establishing and maintaining adequate internal

control over financial reporting. Westlake’s internal control over financial reporting is a process designed to
provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial
statements for external purposes in accordance with generally accepted accounting principles.

Westlake management assessed the effectiveness of the Company’s internal control over financial
reporting as of December 31, 2021. In making this assessment, management used the criteria set forth by the
Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated
Framework (2013). Based on its assessment, Westlake’s management has concluded that the Company’s internal
control over financial reporting was effective as of December 31, 2021 based on those criteria.

During the year ended December 31, 2021, the Company acquired the issued and outstanding equity

interests of certain subsidiaries of Boral Industries engaged in Boral’s North American building products
businesses (“Boral Target Companies”). Because the Company acquired Boral Target Companies during the
current fiscal year, management has excluded Boral Target Companies from the scope of its assessment of the
effectiveness of the Company’s internal control over financial reporting as of December 31, 2021. This exclusion
is in accordance with the general guidance published by the Staff of the SEC that an assessment of a recent
business combination may be omitted from management’s report on internal control over financial reporting in
the first year of consolidation. Boral Target Companies’ total assets and total net sales represented 4.7% and
2.3%, respectively, of the related consolidated financial statement amounts as of and for the year ended
December 31, 2021.

PricewaterhouseCoopers LLP, the independent registered public accounting firm that audited the financial

statements included in this Annual Report on Form 10-K, has also audited the effectiveness of internal control
over financial reporting as of December 31, 2021 as stated in their report that appears on the following page.

66

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Westlake Corporation

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Westlake Corporation (formerly known
as Westlake Chemical Corporation) and its subsidiaries (the “Company”) as of December 31, 2021 and 2020, and
the related consolidated statements of operations, of comprehensive income, of changes in stockholders’ equity
and of cash flows for each of the three years in the period ended December 31, 2021, including the related notes
(collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal
control over financial reporting as of December 31, 2021, based on criteria established in Internal Control—
Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material
respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its
operations and its cash flows for each of the three years in the period ended December 31, 2021 in conformity
with accounting principles generally accepted in the United States of America. Also in our opinion, the Company
maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021,
based on criteria established in Internal Control—Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining

effective internal control over financial reporting, and for its assessment of the effectiveness of internal control
over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial
Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on
the Company’s internal control over financial reporting based on our audits. We are a public accounting firm
registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to
be independent with respect to the Company in accordance with the U.S. federal securities laws and the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we

plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements
are free of material misstatement, whether due to error or fraud, and whether effective internal control over
financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of

material misstatement of the consolidated financial statements, whether due to error or fraud, and performing
procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding
the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the
accounting principles used and significant estimates made by management, as well as evaluating the overall
presentation of the consolidated financial statements. Our audit of internal control over financial reporting
included obtaining an understanding of internal control over financial reporting, assessing the risk that a material
weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on
the assessed risk. Our audits also included performing such other procedures as we considered necessary in the
circumstances. We believe that our audits provide a reasonable basis for our opinions.

67

As described in Management’s Report on Internal Control Over Financial Reporting, management has

excluded certain subsidiaries acquired from Boral Industries engaged in Boral’s North American building
products businesses (“Boral Target Companies”) from its assessment of internal control over financial reporting
as of December 31, 2021 because they were acquired by the Company in a purchase business combination during
2021. We have also excluded the Boral Target Companies from our audit of internal control over financial
reporting. The Boral Target Companies are wholly-owned subsidiaries whose total assets and total net sales
excluded from management’s assessment and our audit of internal control over financial reporting represent
4.7% and 2.3%, respectively, of the related consolidated financial statement amounts as of and for the year ended
December 31, 2021.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in
accordance with generally accepted accounting principles. A company’s internal control over financial reporting
includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance
with generally accepted accounting principles, and that receipts and expenditures of the company are being made
only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the
company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect

misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the
consolidated financial statements that was communicated or required to be communicated to the audit committee
and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and
(ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit
matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we
are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit
matter or on the accounts or disclosures to which it relates.

Acquisition of Boral Target Companies—Valuation of Certain Customer Relationship Intangible Assets

As described in Notes 1 and 2 to the consolidated financial statements, on October 1, 2021, the Company

completed its acquisition of the Boral Target Companies for a total purchase price of $2,132 million. The
Company records business combinations using the acquisition method of accounting. Under the acquisition
method of accounting, identifiable assets acquired and liabilities assumed are recorded at their acquisition date
fair values, which resulted in the recognition of $645 million of customer relationship intangible assets. As
disclosed by management, the fair value of the customer relationships acquired is estimated with a discounted
cash flow model using the multi-period excess earnings methodology, which involves the use of significant
estimates and assumptions related to revenue growth rates, operating margins, discount rates, and customer
attrition rates, among other items.

68

The principal considerations for our determination that performing procedures relating to the valuation of
certain acquired customer relationship intangible assets from the acquisition of the Boral Target Companies is a
critical audit matter are the significant judgment by management in determining the fair value of certain
customer relationship intangible assets; this in turn led to a high degree of auditor judgment, subjectivity, and
effort in performing procedures and evaluating management’s significant assumptions related to revenue growth
rates, operating margins, discount rates, and customer attrition rates. In addition, the audit effort involved the use
of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with

forming our overall opinion on the consolidated financial statements. These procedures included testing the
effectiveness of controls relating to acquisition accounting, including controls over management’s valuation of
certain customer relationship intangible assets and controls over the determination of significant assumptions
related to revenue growth rates, operating margins, discount rates, and customer attrition rates. These procedures
also included, among others, reading the purchase agreement and testing management’s process for estimating
the fair value of certain customer relationship intangible assets. Testing management’s process included
evaluating the appropriateness of the multi-period excess earnings method, testing the completeness and accuracy
of the underlying data, and evaluating the reasonableness of management’s significant assumptions related to
revenue growth rates, operating margins, discount rates, and customer attrition rates. Evaluating the
reasonableness of the revenue growth rates and operating margins involved considering the past performance of

1. Description of Business and Significant Accounting Policies

Description of Business

Westlake Corporation, formerly known as Westlake Chemical Corporation (the “Company”) operates as an

integrated global manufacturer and marketer of performance and essential materials and housing and
infrastructure products. These products include some of the most widely used materials in the world, which are
fundamental to many diverse consumer and industrial markets, including residential construction, flexible and
rigid packaging, automotive products, healthcare products, water treatment, coatings as well as other durable and
non-durable goods. The Company’s customers range from large chemical processors and plastics fabricators to
small construction contractors, municipalities and supply warehouses throughout North America, Europe and
Asia. The industries in which the Company operates are subject to price fluctuations and volatile feedstock
pricing typical of a commodity-based industry, the effects of which may not be immediately passed along to
customers. The Company changed its name from Westlake Chemical Corporation to Westlake Corporation on
February 18, 2022.

Westlake Chemical Partners LP

In 2014, the Company formed Westlake Chemical Partners LP (“Westlake Partners”) to operate, acquire

and develop ethylene production facilities and related assets. Westlake Partners’ assets consist of a limited
partner interest in Westlake Chemical OpCo LP (“OpCo”), as well as the general partner interest in OpCo.
OpCo’s assets include two ethylene production facilities at the Company’s Lake Charles, Louisiana site, one
ethylene production facility at the Company’s Calvert City, Kentucky site and a 200-mile common carrier
ethylene pipeline that runs from Mont Belvieu, Texas to the Company’s Longview, Texas site. As of
December 31, 2021, the Company held a 77.2% limited partner interest in OpCo and a controlling interest in
Westlake Partners. The operations of Westlake Partners are consolidated in the Company’s financial statements.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and subsidiaries in which the

Company directly or indirectly owns more than a 50% voting interest and exercises control and, when applicable,
entities for which the Company has a controlling financial interest or is the primary beneficiary. Investments in
majority-owned companies where the Company does not exercise control and investments in nonconsolidated
affiliates (20%-50% owned companies, joint ventures and partnerships) are accounted for using the equity
method of accounting. Undistributed earnings from joint ventures included in retained earnings were immaterial
as of December 31, 2021. All intercompany transactions and balances are eliminated in consolidation.

Noncontrolling interests represent the direct equity interests held by investors in the Company’s

consolidated subsidiaries, Westlake Partners, Taiwan Chlorine Industries, Ltd. and Suzhou Huasu Plastics Co.,
Ltd.

The Company holds a 50% interest in RS Cogen, LLC (“RS Cogen”) with Entergy Power RS, LLC
(“Entergy”) holding the remaining interest. Effective January 2021, the Company consolidated RS Cogen into its
consolidated financial statements and classified Entergy’s 50% interest in RS Cogen as a component of
noncontrolling interest on the consolidated balance sheet.

(in millions of dollars, except share amounts and per share data)

Recasting of Certain Prior Period Information

The Company has historically operated in two principal operating segments, Vinyls and Olefins. In the
fourth quarter of 2021, the Company reorganized its business into two principal operating segments, Performance
and Essential Materials and Housing and Infrastructure Products. The Olefins, PVC, VCM, chlorine, caustic soda
and chlorinated derivative materials and polyethylene are included in the Performance and Essential Materials
segment. Building products, pipe and fittings and PVC compounds are included in the Housing and Infrastructure
Products segment. These reporting changes have been retrospectively reflected in the segment results for all
periods presented.

Certain reclassifications have been made to the prior-year financial statements to conform to the current

year presentation.

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with the accounting

principles generally accepted in the United States.

Cash and Cash Equivalents

Cash equivalents consist of highly liquid investments that are readily convertible into cash and have a

maturity of three months or less at the date of acquisition.

Concentration of Credit Risk

Financial instruments which potentially subject the Company to concentration of risk consist principally of

trade receivables from customers engaged in manufacturing polyethylene products, polyvinyl chloride (“PVC”)
products and PVC pipe products. The Company performs periodic credit evaluations of the customers’ financial
condition and generally does not require collateral. The Company maintains allowances for potential losses.

Allowance for Credit Losses

The determination of the allowance for credit losses is based on estimation of the amount of accounts
receivable that the Company believes are unlikely to be collected. Estimating this amount requires analysis of the
financial strength of the Company’s customers, the use of historical experience, the Company’s accounts
receivable aged trial balance, customer specific collectability analysis and an evaluation of economic conditions.
The allowance for credit losses is reviewed quarterly. Past due balances over 90 days and high-risk accounts as
determined by the analysis of financial strength of customers are reviewed individually for collectability.

Inventories

Inventories primarily include product, material and supplies. Inventories are stated at lower of cost or net

realizable value. Cost is determined using the first-in, first-out (“FIFO”) or average method.

Property, Plant and Equipment

Property, plant and equipment are carried at cost, net of accumulated depreciation. Cost includes

expenditures for improvements and betterments that extend the useful lives of the assets and interest capitalized
on significant capital projects. Capitalized interest was $3, $4 and $9 for the years ended December 31, 2021,
2020 and 2019, respectively. Repair and maintenance costs are charged to operations as incurred. Gains and
losses on the disposition or retirement of fixed assets are reflected in the consolidated statement of operations
when the assets are sold or retired.

Depreciation is provided by utilizing the straight-line method over the estimated useful lives of the assets

as follows:

Impairment of Long-Lived Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances
indicate that the carrying amount of an asset may not be recoverable. Long-lived assets assessed for impairment
are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of
other assets and liabilities. Recoverability of assets to be held and used is measured by a comparison of the
carrying amount of an asset to future net undiscounted cash flows expected to be generated by the asset. Assets
are considered to be impaired if the carrying amount of an asset exceeds the future undiscounted cash flows. The
impairment recognized is measured by the amount by which the carrying amount of the assets exceeds the fair
value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or estimated fair
value less costs to sell.

Impairment of Goodwill and Intangible Assets

Goodwill is tested for impairment at least annually, or when events or changes in circumstances indicate

the fair value of a reporting unit with goodwill has been reduced below its carrying value. The Company
performed impairment tests for the Performance and Essential Materials and Housing and Infrastructure Products
segments’ goodwill in October 2021, and the impairment tests indicated that the recorded goodwill was not
impaired. There has been no impairment of the goodwill since the goodwill was initially recorded. Other
intangible assets with finite lives are amortized over their estimated useful lives and reviewed for impairment in
accordance with the provisions of the accounting guidance. See Note 8 for more information on the Company’s
annual goodwill impairment tests.

Equity Method Investments

The Company accounts for investments using the equity method of accounting if the Company has the
ability to exercise significant influence over, but not control of, an investee. Significant influence generally exists

77

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(in millions of dollars, except share amounts and per share data)

if the Company has an ownership interest representing between 20% and 50% of the voting rights. Under the
equity method of accounting, investments are stated initially at cost and are adjusted for subsequent additional
investments and the proportionate share of profit or losses and distributions. The Company records its share of
the profits or losses of the equity investments, net of income taxes, in the consolidated statements of income. The
equity method investments are evaluated for impairment when events or changes in circumstances indicate, in
management’s judgment, that the carrying value of such investments may have experienced an other-than-
temporary decline in value. When evidence of loss in value has occurred, management compares the estimated
fair value of investment to the carrying value of investment to determine whether an impairment has occurred. If
the estimated fair value is less than the carrying value and management considers the decline in value to be other-
than-temporary, the excess of the carrying value over the estimated fair value is recognized in the consolidated
financial statements as an impairment.

Other Assets, net

Other assets, net include turnaround costs, investments in unconsolidated subsidiaries, restricted cash,

deferred charges and other long-term assets.

The Company accounts for turnaround costs under the deferral method. Turnarounds are the scheduled and

required shutdowns of specific operating units in order to perform planned major maintenance activities. The
costs related to the significant overhaul and refurbishment activities include maintenance materials, parts and
direct labor costs. The costs of the turnaround are deferred when incurred at the time of the turnaround and
amortized (within depreciation and amortization) on a straight-line basis until the next planned turnaround, which
typically range from three to six years. Deferred turnaround costs are presented as a component of other assets,
net. The cash outflows related to these costs are included in operating activities in the consolidated statement of
cash flows.

Business Combinations

The Company records business combinations using the acquisition method of accounting. Under the
acquisition method of accounting, identifiable assets acquired and liabilities assumed are recorded at their
acquisition date fair values. The excess of the purchase price over the estimated fair value is recorded as
goodwill. Changes in the estimated fair values of net assets recorded for acquisitions prior to the finalization of
more detailed analysis, but not to exceed one year from the date of acquisition, will adjust the amount of the
purchase price allocable to goodwill. Measurement period adjustments are reflected in the period in which they
occur.

Income Taxes

The Company utilizes the liability method of accounting for deferred income taxes. Under the liability
method, deferred tax assets or liabilities are recorded based upon temporary differences between the tax basis of
assets and liabilities and their carrying values for financial reporting purposes. Deferred tax expense or benefit is
the result of changes in the deferred tax assets and liabilities during the period. Valuation allowances are
recorded against deferred tax assets when it is considered more likely than not that the deferred tax assets will not
be realized.

(in millions of dollars, except share amounts and per share data)

Foreign Currency Translation

Assets and liabilities of foreign subsidiaries are translated to U.S. dollars at the exchange rate as of the end

of the year. Statement of operations items are translated at the average exchange rate for the year. The resulting
translation adjustment is recorded as a separate component of stockholders’ equity.

Revenue Recognition

Revenue is recognized when the Company transfers control of inventories to its customers. Amounts

recognized as revenues reflect the consideration to which the Company expects to be entitled in exchange for
those inventories. Provisions for discounts, rebates and returns are incorporated in the estimate of variable
consideration and reflected as a reduction to revenue in the same period as the related sales.

Control of inventories generally transfers upon shipment for domestic sales. The Company excludes taxes

collected on behalf of customers from the estimated contract price. For export contracts, the point at which
control passes to the customer varies depending on the terms specified in the customer contract.

The Company generally invoices customers and recognizes revenue and accounts receivable upon

transferring control of inventories. In limited circumstances, the Company transfers control of inventories shortly
before it has an unconditional right to receive consideration, resulting in recognition of contract assets. The
Company also receives advance payments from certain customers, resulting in recognition of contract liabilities.
Contract assets and liabilities are generally settled within the period and are not material to the consolidated
balance sheets. The Company expenses sales commissions when incurred. These costs are recorded within
selling, general and administrative expenses. Aside from the amounts disclosed within Note 9, the Company does
not disclose the value of unsatisfied performance obligations because its contracts with customers (1) have an
original expected duration of one year or less or (2) have only variable consideration that is calculated based on
market prices at specified dates and is allocated to wholly unsatisfied performance obligations.

ASU No. 2014-09, Revenue from Contracts with Customers (“ASC 606”) requires disclosure of
disaggregated revenue into categories that depict the nature of how the Company’s revenue and cash flows are
affected by economic factors. The Company discloses revenues by business and segment in Note 23.

Leases

The Company is obligated under various long-term and short-term operating leases for rail cars, buildings,

land and other transportation and storage assets. The Company determines whether an arrangement is, or
contains, a lease at contract inception. Some of the Company’s arrangements contain both lease and non-lease
components. For certain transportation equipment leases, the Company accounts for the lease and non-lease
components as a single lease component. The Company records right-of-use assets and corresponding lease
liabilities for operating leases with terms greater than one year. Operating lease right-of-use assets and liabilities
are recorded at the present value of the fixed lease payments over the life of the lease. The majority of the
Company’s leases do not provide an implicit rate. Therefore, the Company uses its incremental borrowing rate at
lease commencement to measure operating lease right-of-use assets and lease liabilities. Certain of the

79

(in millions of dollars, except share amounts and per share data)

Company’s leases provide for renewal and purchase options. Renewal and purchase options are evaluated at
lease commencement and included in the lease term if they are reasonably certain to be exercised. Short-term
leases are recognized in rental expense on a straight-line basis over the lease term and are not recorded in the
consolidated balance sheets. The Company’s finance leases are not material to the consolidated financial
statements.

Transportation and Freight

Amounts billed to customers for freight and handling costs on outbound shipments are included in net sales

in the consolidated statements of operations. Transportation and freight costs incurred by the Company on
outbound shipments are included in cost of sales in the consolidated statements of operations.

Price Risk Management

The Company recognizes derivative instruments on the balance sheet at fair value, and changes in a

derivative’s fair value are currently recognized in earnings or comprehensive income, depending on the
designation of the derivative. If the derivative is designated as a fair value hedge, the changes in the fair value of
the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative
is designated as a cash flow hedge, the effective portion of the change in the fair value of the derivative is
recorded in comprehensive income and is recognized in the statement of operations when the hedged item affects
earnings. Ineffective portions of changes in the fair value of cash flow hedges are recognized in earnings
currently. The derivative instruments did not have a material impact on the Company’s consolidated financial
statements.

Asset Retirement Obligations

The Company has conditional asset retirement obligations for the removal and disposal of hazardous

materials from certain of the Company’s manufacturing facilities.

The Company recognizes asset retirement obligations in the period in which the liability becomes probable

and reasonably estimable. Recognized asset retirement obligations are initially recorded at fair value and
capitalized as a component of the carrying value of the long-lived asset to which the obligation relates. The
liability is accreted to its future value each period, and the capitalized cost is depreciated over the estimated
useful life of the related asset. Upon settlement of the liability, a gain or loss is recorded. As of December 31,
2021, the Company had $1 and $23 of asset retirement obligations recorded as accrued and other liabilities and
other liabilities, respectively. As of December 31, 2020, the Company had $12 and $17 of asset retirement
obligations recorded as accrued and other liabilities and other liabilities, respectively.

The Company also has conditional asset retirement obligations that have not been recognized because the

fair values of the conditional legal obligations cannot be measured due to the indeterminate settlement date of the
obligations. Settlements of the unrecognized conditional asset retirement obligations are not expected to have a
material adverse effect on the Company’s financial condition, results of operations or cash flows in any
individual reporting period.

Environmental Costs

Environmental costs relating to current operations are expensed or capitalized, as appropriate, depending
on whether such costs provide future economic benefits. Remediation liabilities are recognized when the costs
are considered probable and can be reasonably estimated. Measurement of liabilities is based on currently
enacted laws and regulations, existing technology and undiscounted site-specific costs. Environmental liabilities
in connection with properties that are sold or closed are realized upon such sale or closure, to the extent they are
probable and estimable and not previously reserved. Recognition of any joint and several liabilities is based upon
the Company’s best estimate of its final pro rata share of the liability.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the

United States of America 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 from those estimates.

The coronavirus (“COVID-19”) pandemic resulted in widespread adverse impacts on the global economy

in 2020. As the COVID-19 pandemic and its impacts on the global economy continue, the Company may
experience impacts on its business operations. However, the impact that COVID-19 will have on the financial
condition, results of operations and cash flows of the Company 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 globally and the efficacy of the available vaccines (including with respect to the more
recent variants of COVID-19), vaccine hesitancy and the availability of 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, actions taken by customers, suppliers and other third parties,
workforce availability, and the timing and extent to which normal economic and operating conditions resume.

Recent Accounting Pronouncements

Business Combinations—Accounting for Contract Assets and Contract Liabilities from Contracts with Customers
Update (ASU No.2021-08)

In October 2021, the Financial Accounting Standards Board (“FASB”) issued an accounting standards

update that requires acquiring entities to recognize and measure contract assets and contract liabilities in a
business combination in accordance with the accounting guidance on Revenue from Contracts with Customers
(ASC 606). The guidance in this update improves comparability for both the recognition and measurement of
acquired revenue contracts with customers at the date of and after a business combination. The accounting
standard will be effective for reporting periods beginning after December 15, 2022. Early adoption of the
guidance is permitted. The Company is in the process of evaluating the impact of this standard on the Company’s
consolidated financial position, results of operations and cash flows.

Recently Adopted Accounting Standards

Income Taxes (ASU No. 2019-12)

In December 2019, the FASB issued an accounting standards update removing certain exceptions for
investments, intraperiod allocations and interim calculations and adding guidance to reduce complexity in
accounting for income taxes. The accounting standard became effective for reporting periods beginning after
December 15, 2020. The Company adopted this accounting standard effective January 1, 2021, and the adoption
did not have a material impact on the Company’s consolidated financial position, results of operations and cash
flows.

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 from March 12, 2020 through December 31, 2022. The Company adopted this accounting
standard effective October 1, 2021, and the adoption did not have a material impact on the Company’s
consolidated financial position, results of operations and cash flows.

2. Acquisitions

Boral Target Companies in North America.

On June 20, 2021, the Company, through a wholly-owned subsidiary, entered into an Equity Purchase

Agreement (the “Boral Purchase Agreement”) by and among Boral Building Products Inc., a Michigan
corporation, Boral Stone Products LLC, a Delaware limited liability company, Boral Lifetile Inc., a California
corporation, Boral Windows LLC, a Utah limited liability company, Boral Industries Inc., a California
corporation (“Boral Industries”), and solely for the limited purposes set forth therein, the Company, and Boral
Limited, an Australian corporation (“Boral”). Pursuant to the terms of the Boral Purchase Agreement, the
Company agreed to acquire from Boral Industries all of the issued and outstanding equity interests of certain
subsidiaries of Boral Industries engaged in Boral’s North American building products businesses in roofing,
siding, trim and shutters, decorative stone and windows (the “Boral Target Companies”) for a purchase price of
$2,150 in cash, subject to working capital post-closing adjustments. The Boral Purchase Agreement also includes
a potential earn-out payment from the Company to Boral Industries of up to $65 if the windows division of the
Boral Target Companies generates EBITDA in excess of a specified target in its fiscal year ending June 30, 2024.
On October 1, 2021, the Company completed its acquisition of, Boral Target Companies (the “Boral
Acquisition”) for a total purchase price of $2,132 in an all-cash transaction and accounted for the acquisition
under the business combination method in accordance with Accounting Standard Codification Topic 805 (“ASC
805”), Business Combinations. The Boral Target Companies acquisition is consistent with the Company’s
vertical integration strategy of enhancing margin stability and downstream products. The additional product lines
through the acquisition will broaden the Company’s footprint in the fast-growing housing markets in North
America. The assets acquired and liabilities assumed and the results of operations of Boral Target Companies are
included in the Housing and Infrastructure Products segment.

For the year ended December 31, 2021, the Company recognized acquisition-related costs of $17 for
advisory, consulting and professional fees, and other expenses that were expensed as restructuring, transaction
and integration-related costs as a component of the income from operations.

The following table summarizes the fair value of identified assets acquired and liabilities assumed at the

date of acquisition. The preliminary allocation of consideration transferred is based on management’s estimates,
judgments and assumptions. These estimates, judgments and assumptions are subject to change upon final
valuation and should be treated as preliminary values. Management estimated that consideration paid exceeded
the fair value of the net assets acquired. Therefore, goodwill of $771 was recorded, most of which will not be
deductible for income tax purposes. The goodwill is assigned to the Company’s Housing and Infrastructure
Products segment. The final allocation of purchase consideration could include changes in the estimated fair
value of (1) inventories; (2) property, plant and equipment; (3) intangible assets comprising of customer
relationships, trade names, developed technologies; (4) deferred income taxes; and (5) other assets.

(in millions of dollars, except share amounts and per share data)

The excess of the total equity value of Boral based on the purchase consideration over net assets acquired

was recorded as goodwill. The goodwill is primarily attributable to the synergies expected to arise after the
acquisition. The synergies relate to enhanced leading positions in the home building products and materials
sector and increased margin stability.

The following table summarizes the components of identifiable intangible assets acquired and their

estimated useful lives as of the acquisition date:

Trade name . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $

There are no indefinite-lived intangible assets derived acquired as a result of the Boral Target Companies

acquisition. Definite lived intangible assets acquired as a result of the Boral acquisition are amortized on a
straight-line basis to reflect the pattern in which the economic benefits of the intangible assets are realized.

The fair value for Trade name and Technology were estimated using the income approach, specifically the
relief-from-royalty method which estimates the cost savings that accrue to the owner of the intangible assets that
would otherwise be payable as royalties or licenses fees on revenues earned through the use of the asset. The fair
value of Customer Relationships was estimated using the multi-period excess earnings method. The excess
earning method model estimates revenues and cash flows derived from the asset and then deducts portions of the
cash flow that can be attributed to supporting assets. The resulting cash flow, which is attributable solely to the
asset acquired, is then discounted at a rate of return commensurate with the risk of the asset to calculate the
present value.

Unaudited Pro Forma Financial Information

The acquired Boral Target Companies contributed net revenues and net loss of $275 and $15, respectively,
to the Company for the period from October 1, 2021 to December 31, 2021. The following unaudited pro forma

January 1, 2020:

LASCO Fittings, Inc.

On July 4, 2021, the Company, through a wholly-owned subsidiary, entered into an Equity Purchase
Agreement with Aalberts U.S. Holding Corp., a Delaware corporation (“Aalberts”) and wholly-owned subsidiary
of Aalberts N.V., pursuant to which, the Company, agreed to acquire LASCO Fittings, Inc., a Delaware
corporation (“LASCO”), from Aalberts. LASCO is a manufacturer of injected-molded PVC fittings that serve the
plumbing, pool and spa, industrial, irrigation and retail markets in the United States. On August 19, 2021, the
Company completed its acquisition of, and acquired all of the equity interests in, LASCO (the “LASCO
Acquisition”). The total closing purchase consideration was $277. The acquisition is being accounted for under
the acquisition method of accounting. The assets acquired and liabilities assumed and the results of operations of
LASCO are included in the Housing and Infrastructure Products segment. LASCO net sales and net income since
the acquisition date and the acquisition-related costs recognized in the consolidated statement of operations for
the year ended December 31, 2021 were not material to the Company’s consolidated statement of operations. The
pro forma impact of this acquisition has not been presented as it is not material to the Company’s consolidated
statements of operations for the years ended December 31, 2021 and 2020. The Company recognized intangible
assets of $77, of which $50 is included in customer relationships, net on the Company’s consolidated balance
sheets as of December 31, 2021, and goodwill of $106 with the remainder of the purchase consideration
primarily allocated to property, plant, and equipment, net and working capital balances. The goodwill is expected
to be deductible for income tax purposes. The goodwill recognized is primarily attributable to the expected value
to be achieved from the acquisition synergies. The intangible assets that have been acquired are being amortized
over a period of 17 to 18 years.

Dimex LLC.

On August 2, 2021, the Company, through a wholly-owned subsidiary, entered into a Stock Purchase
Agreement with DX Acquisition Corp., a Delaware corporation (“Dimex”), each of Dimex’s stockholders, and
for limited purposes, the Company and Grey Mountain Partners Fund III Holdings, L.P., pursuant to which the
Company agreed to acquire Dimex. Dimex is a producer of various consumer products made from post-
industrial-recycled polyvinyl chloride, polyethylene and thermoplastic elastomer materials, including landscape
edging; industrial, home and office matting; marine dock edging; and masonry joint controls. On September 10,
2021, the Company completed its acquisition of, and acquired all of the equity interests in, Dimex (the “Dimex
Acquisition” and, together with the Boral Acquisition and the LASCO Acquisition, the “2021 Acquisitions”).
The total closing purchase consideration was $172. The acquisition is being accounted for under the acquisition
method of accounting. The assets acquired and liabilities assumed and the results of operations of Dimex are
included in the Housing and Infrastructure Products segment. Dimex net sales and net income since the
acquisition date and the acquisition-related costs recognized in the consolidated statement of operations for the
year ended December 31, 2021 were not material to the Company’s consolidated statement of operations. The
pro forma impact of this acquisition has not been presented as it is not material to the Company’s consolidated
statements of operations for the years ended December 31, 2021 and 2020. The Company recognized intangible

assets of $69, of which $45 is included in customer relationships, net on the Company’s consolidated balance
sheets as of December 31, 2021, and goodwill of $66, most of which will not be deductible for income tax
purposes, with the remainder of the purchase consideration primarily allocated to property, plant, and equipment,
net and working capital balances. The goodwill is primarily attributable to the expected value to be achieved
from the acquisition synergies. The intangible assets that have been acquired are being amortized over a period of
17 to 19 years.

Hexion Epoxy Business.

On November 24, 2021, the Company, through a wholly-owned subsidiary, entered into a Stock Purchase

Agreement (the “Hexion Purchase Agreement”) by and among Hexion Inc. (“Hexion”), an Ohio corporation, and
solely for the limited purposes set forth therein, the Company. Pursuant to the terms of the Hexion Purchase
Agreement, the Company agreed to acquire Hexion’s global epoxy business for a purchase price of
approximately $1,200 in cash, subject to certain closing date adjustments as set forth in the Hexion Purchase
Agreement (the “Hexion Acquisition”). On February 1, 2022, the Company completed the acquisition of, and
acquired all of the equity interests in, the Hexion Acquisition. The assets acquired and liabilities assumed and the
results of operations of Hexion’s global epoxy business will be included in the Performance and Essential
Materials segment. Due to the recent closing of this acquisition, certain financial information related to this
acquisition, including the fair value of total consideration transferred or estimated to be transferred, is not yet
finalized.

3. Financial Instruments

Restricted Cash and Cash Equivalents

The Company had restricted cash and cash equivalents of $33 and $24 at December 31, 2021 and 2020,

As part of the reorganization of operating segments, the Company assessed and re-defined reporting units

effective as of the beginning of the fourth quarter of 2021, including reallocation of goodwill on a relative fair
value basis as applicable to affected reporting units. Goodwill impairment analyses were performed as of the
effective reorganization date both before and after the reorganization. The fair values of the reporting units were
determined using both a discounted cash flow methodology and a market value methodology. Based upon this
assessment, the Company determined that it was more likely than not that the fair value of the reporting units
exceeds its carrying value both prior to the reorganization and after the reorganization.

The discounted cash flow projections were based on a long-term forecast to reflect the cyclicality of the

Company’s businesses. The forecast was based on prices and spreads projected by IHS Markit (“IHS”), a
chemical industry organization offering market and business advisory services for the chemical market, historical
results and estimates by management, including its strategic and operational plans. Other significant assumptions
used in the discounted cash flow projection included projected sales volumes based on production capacities. The
future cash flows were discounted to present value using a discount rate ranging from 8.8% to 10.8%. The
significant assumptions used in determining the fair values of the reporting units using the market value
methodology include the determination of appropriate market comparables and the estimated multiples of net
income before interest expense, income taxes, depreciation and amortization (“EBITDA”) a willing buyer is
likely to pay.

Prior to the reorganization of the operating segments, the Company performed its annual impairment
analysis for the legacy Vinyls segment reporting units during the second quarter of 2021, and determined that it
was more likely than not that the fair value of each of the Vinyls segment reporting units exceeds its carrying
value.

9. Equity Method Investments

LACC, LLC Joint Venture

In 2015, Eagle US 2 LLC (“Eagle”), a wholly-owned subsidiary of the Company, and Lotte Chemical USA

Corporation, a subsidiary of Lotte Chemical Corporation (“Lotte”), formed a joint venture, LACC, LLC
(“LACC”), to design, build and operate an ethylene facility with 2.2 billion pounds per year of ethylene
production capacity. Pursuant to a contribution and subscription agreement between Eagle and LACC, Eagle
contributed $225 to LACC to fund construction costs of the ethylene plant, representing approximately 12% of
the membership interests in LACC.

On November 12, 2019, the Company, through Eagle, completed the acquisition of an additional 34.8% of

the membership interests in LACC from Lotte for approximately $817. In January 2022, the Company notified
Lotte of its exercise of an option to acquire an additional 3.2% of the membership interests in LACC from Lotte
for approximately $90. As of December 31, 2021, the Company’s investment exceeded the underlying equity in
net assets by approximately $166 which was assigned to goodwill and not amortized.

The ethylene plant was built adjacent to the Company’s chlor-alkali facility in Lake Charles. During the

third quarter of 2019, the ethylene plant began commercial operations.

The Company accounts for its investment in LACC under the equity method of accounting. The LACC
joint venture is a cost-sharing arrangement between the members of LACC. The members of LACC receive their
proportionate shares of ethylene offtake each month and fund cash operating costs, excluding depreciation and
amortization. As a result, LACC recognizes net losses equal to depreciation and amortization each period. The
Company’s equity in losses from LACC, which is equal to its share of depreciation and amortization expenses, is
recognized in cost of sales in the consolidated statements of operations. The Company’s investment in LACC is

90

WESTLAKE CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(in millions of dollars, except share amounts and per share data)

recorded as a component of equity method investments in the consolidated balance sheets. The Company’s
capital contributions to fund its share of capital expenditures are classified within investing activities in the
consolidated statements of cash flows.

The Company’s ethylene offtake from LACC was approximately 909 million and 787 million pounds

during the years ended December 31, 2021 and 2020, respectively.

Changes in the Company’s investment in LACC for the years ended December 31, 2021 and 2020 were as

Services Provided to LACC and Lotte

The Company provides certain utilities and other services to LACC and Lotte. Pursuant to a construction
and reimbursement agreement, LACC and Lotte agreed to reimburse the Company for construction costs over a
6.5-year period beginning in 2020. In addition to the reimbursements for construction costs, the Company
charges LACC and Lotte certain fixed fees under an operating, maintenance and logistics agreement. The
Company accounts for the reimbursement of construction costs and the fixed fees as components of the total
transaction price and recognizes it ratably in net sales over approximately 25 years. The remaining performance
obligations at December 31, 2021, representing these fixed components of the transaction price, totaled $55 and
$76 from LACC and Lotte, respectively. The associated contract liabilities recorded from LACC and Lotte
totaled $14 and $18 as of December 31, 2021, respectively, and $10 and $12 as of December 31, 2020,
respectively. In addition to the reimbursements for construction costs and other fixed fees, the Company charges

Credit Agreement

On July 24, 2018, the Company entered into a new $1,000 revolving credit facility that is scheduled to

mature on July 24, 2023 (the “Credit Agreement”) and, in connection therewith, terminated the previous $1,000
revolving credit facility that was scheduled to mature on August 23, 2021 (the “Prior Credit Agreement”). The
Credit Agreement bears interest at either (a) LIBOR plus a spread ranging from 1.00% to 1.75% or (b) Alternate
Base Rate plus a spread ranging from 0.00% to 0.75% in each case depending on the credit rating of the
Company. At December 31, 2021, the Company had no borrowings outstanding under the Credit Agreement. As
of December 31, 2021, the Company had no outstanding letters of credit and had $1,000 of borrowing
availability under the Credit Agreement. The Credit Agreement contains certain affirmative and negative
covenants, including a quarterly total leverage ratio financial maintenance covenant. As of December 31, 2021,
the Company was in compliance with the total leverage ratio financial maintenance covenant. The Credit
Agreement also contains certain events of default and if and for so long as certain events of default have occurred
and are continuing, any overdue amounts outstanding under the Credit Agreement will accrue interest at an
increased rate, the lenders can terminate their commitments thereunder and payments of any outstanding amounts
could be accelerated by the lenders.

The Credit Agreement includes a $150 sub-limit for letters of credit, and any outstanding letters of credit

will be deducted from availability under the facility. The Credit Agreement also provides for a discretionary $50
commitment for swingline loans to be provided on a same-day basis. The Company may also increase the size of
the facility, in increments of at least $25, up to a maximum of $500, subject to certain conditions and if certain
lenders agree to commit to such an increase.

3.60% Senior Notes due 2022

In July 2012, the Company issued $250 aggregate principal amount of the 3.60% 2022 Senior Notes. The

3.60% 2022 Senior Notes are unsecured and were issued with an original issue discount of $1. There is no
sinking fund and no scheduled amortization of the 3.60% 2022 Senior Notes prior to maturity. The Company
may optionally redeem the 3.60% 2022 Senior Notes in accordance with the terms of the 3.60% 2022 Senior
Notes.

0.875% Senior Notes due 2024

In August 2021, the Company completed the registered public offering of $300 aggregate principal amount

of the 0.875% 2024 Senior Notes. The Company may optionally redeem the 0.875% 2024 Senior Notes at any
time and from time to time on or after August 15, 2022 for 100% of the principal amount plus accrued and
unpaid interest. The holders of the 0.875% 2024 Senior Notes may require us to repurchase the 0.875% 2024
Senior Notes at a price of 101% of their principal amount, plus accrued and unpaid interest to, but not including,
the date of repurchase, upon the occurrence of both a “change of control” and, within 60 days of such change of
control, a “below investment grade rating event” (as such terms are defined in the indenture governing the
0.875% 2024 Senior Notes).

3.60% Senior Notes due 2026 and 5.0% Senior Notes due 2046

In August 2016, the Company issued $750 aggregate principal amount of the 3.60% 2026 Senior Notes and

$700 aggregate principal amount of the 5.0% 2046 Senior Notes. In March 2017, the Company commenced
registered exchange offers to exchange the 3.60% 2026 Senior Notes and the 5.0% 2046 Senior Notes for new
notes that are identical in all material respects to the 3.60% 2026 Senior Notes and the 5.0% 2046 Senior Notes,
except that the offer and issuance of the new Securities and Exchange Commission-registered notes have been
registered under the Securities Act of 1933, as amended (the “Securities Act”). The exchange offers expired on
April 24, 2017, and approximately 99.97% of the 3.60% 2026 Senior Notes and 100% of the 5.0% 2046 Senior
Notes were exchanged. The 3.60% 2026 Senior Notes that were not exchanged in the 3.60% 2026 Senior Notes
exchange offer have not been registered under the Securities Act or any state securities laws and may not be
offered or sold in the U.S. absent registration or an applicable exemption from registration requirements or a
transaction not subject to the registration requirements of the Securities Act or any state securities law.

Revenue Bonds

In December 1997, the Company entered into a loan agreement with a public trust established for public
purposes for the benefit of the Parish of Calcasieu, Louisiana. The public trust issued $11 principal amount of
tax-exempt waste disposal revenue bonds in order to finance the Company’s construction of waste disposal
facilities for an ethylene plant. The waste disposal revenue bonds expire in December 2027 and are subject to
redemption and mandatory tender for purchase prior to maturity under certain conditions. The interest rate on the
waste disposal revenue bonds at December 31, 2021 and 2020 was 0.14% and 0.14%, respectively.

customary events of default and covenants that, among other things and subject to certain exceptions, restrict us
and certain of the Company’s subsidiaries’ ability to (1) incur certain secured indebtedness, (2) engage in certain
sale and leaseback transactions and (3) consolidate, merge or transfer all or substantially all of its assets. The
Notes are unsecured and none of the Company’s subsidiaries have guaranteed any series of the Notes.

As of December 31, 2021, the Company was in compliance with all of its long-term debt covenants.

The weighted average interest rate on all long-term debt was 3.2% and 3.4% at December 31, 2021 and

2020, respectively. Unamortized debt issuance costs on long-term debt were $42 and $28 at December 31, 2021
and 2020, respectively.

Aggregate scheduled maturities of long-term debt during the next five years consist of $269 in 2022, $300

in 2024, and $759 in 2026. There are no other scheduled maturities of debt in 2022 through 2026.

12. Stockholders’ Equity

The Company’s Board of Directors has declared regular quarterly dividends to holders of its common stock

aggregating $145, $137 and $132 for the years ended December 31, 2021, 2020 and 2019, respectively.

Common Stock

Each share of common stock entitles the holder to one vote on all matters on which holders are permitted to

vote, including the election of directors. There are no cumulative voting rights. Accordingly, holders of a
majority of the total votes entitled to vote in an election of directors will be able to elect all of the directors
standing for election. Subject to preferences that may be applicable to any outstanding preferred stock, the
holders of the common stock will share equally on a per share basis any dividends when, as and if declared by
the Board of Directors out of funds legally available for that purpose. If the Company is liquidated, dissolved or
wound up, the holders of the Company’s common stock will be entitled to a ratable share of any distribution to
stockholders, after satisfaction of all the Company’s liabilities and of the prior rights of any outstanding class of
the Company’s preferred stock. The Company’s common stock has no preemptive or conversion rights or other
subscription rights. There are no redemption or sinking fund provisions applicable to the Company’s common
stock.

Preferred Stock

The Company’s charter authorizes the issuance of shares of preferred stock. The Company’s Board of

Directors has the authority, without shareholder approval, to issue preferred shares from time to time in one or
more series, and to fix the number of shares and terms of each such series. The Board may determine the
designations and other terms of each series including dividend rates, whether dividends will be cumulative or
non-cumulative, redemption rights, liquidation rights, sinking fund provisions, conversion or exchange rights and
voting rights.

Stock Repurchase Program

In November 2014, the Company’s Board of Directors approved a $250 share repurchase program (the
“2014 Program”). In November 2015, the Company’s Board of Directors approved the expansion of the 2014

98

WESTLAKE CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(in millions of dollars, except share amounts and per share data)

Program by an additional $150. In August 2018, the Company’s Board of Directors approved the expansion of
the 2014 Program by an additional $150. The number of shares repurchased by the Company under the 2014
Program was 355,800, 995,529 and 517,712 for the years ended December 31, 2021, 2020 and 2019,
respectively. As of December 31, 2021, the Company had repurchased a total of 7,431,520 shares of its common
stock for an aggregate purchase price of approximately $449.

Any shares repurchased under the 2014 Program are held by the Company as treasury stock and may be

used for general corporate purposes, including for the 2013 Omnibus Incentive Plan. In 2014, the Company
began delivering treasury shares to employees and non-employee directors for options exercised and for the
settlement of restricted stock units. The cost of treasury shares delivered is determined using the specific
identification method.

14. Employee Benefits

Defined Contribution Plans

U.S. Plans

The Company has a defined contribution savings plan covering the eligible U.S. regular full-time and part-

time employees, whereby eligible employees may elect to contribute up to 100% of their annual eligible
compensation, subject to an annual plan limit in line with the annual elective contribution limit as determined by
the Internal Revenue Service. The Company matches its employee’s contribution up to a certain percentage of
such employee’s compensation, per the terms of the plan. The Company may, at its discretion and per the terms
of the plan, make an additional non-matching contribution in an amount as the Board of Directors may
determine. For the years ended December 31, 2021, 2020 and 2019, the Company recorded approximately $24,
$21 and $20, respectively, to expense for these contributions.

Further, within the plan, the Company also makes an annual retirement contribution to substantially all
employees of certain subsidiaries. The Company’s contributions to the plan are determined as a percentage of

99

WESTLAKE CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(in millions of dollars, except share amounts and per share data)

employees’ pay. For the years ended December 31, 2021, 2020 and 2019, the Company charged approximately
$35, $34 and $32, respectively, to expense for these contributions.

Non-U.S. Plans

The Company has defined contribution plans in several countries covering eligible employees of the
Company. The Company’s contributions to the plans are based on applicable laws in each country. Contributions
to the Company’s non-U.S. defined contribution plans are made by both the employee and the Company. For the
years ended December 31, 2021, 2020 and 2019, the Company charged approximately $4, $4 and $4,
respectively, to expense for its contributions to these plans.

Defined Benefit Plans

U.S. Plans

The Company has noncontributory defined benefit pension plans that cover certain eligible salaried and

wage employees of certain subsidiaries. However, eligibility for the Company’s plans has been frozen. Benefits
for salaried employees under these plans are based primarily on years of service and employees’ pay near
retirement. Benefits for wage employees are based upon years of service and a fixed amount as periodically
adjusted. The Company recognizes the years of service prior to the Company’s acquisition of the subsidiary’s
facilities for purposes of determining vesting, eligibility and benefit levels for certain employees of the
subsidiary and for determining vesting and eligibility for certain other employees of the subsidiary. The
measurement date for these plans is December 31.

Non-U.S. Plans

The Company has defined benefit pension plans covering current and former employees associated with

the Company’s operations. These pension plans are closed to new participants. Benefits for employees for these
plans are based primarily on employees’ pay near retirement. The majority of these pension plans are unfunded
and have no plan assets. The measurement date for the non-U.S. plans is December 31.

(1) After-tax totals for pension benefits were $21 and $(24) for 2021 and 2020, respectively, and are reflected

in stockholders’ equity as accumulated other comprehensive income (loss).

In the U.S., the Pension Protection Act of 2006 (the “Pension Protection Act”) established a relationship

between a qualified pension plan’s funded status and the actual benefits that can be provided. Restrictions on
plan benefits and additional funding and notice requirements are imposed when a plan’s funded status is less than
certain threshold levels. For the 2021 plan year, the funded status for the Company’s U.S. pension plans are
above 80% and, as such, are exempt from the Pension Protection Act’s benefit restrictions.

Pension plans with an accumulated benefit obligation in excess of plan assets at December 31 are as

discount curve and applying spot rates from the curve to each year of expected benefit payments to determine the
appropriate discount rate for the Company. The assumed long-term return on plan assets is estimated by
considering factors such as the plan’s overall investment strategy, current economic conditions and historical
averages.

The Company’s U.S. pension plan investments are held in the Westlake Defined Benefit Plan. The
Company’s overall investment strategy for these pension plan assets is to achieve a balance between moderate
income generation and capital appreciation. The investment strategy includes a mix of approximately 60% of
investments for long-term growth, and 40% for near-term benefit payments with a diversification of asset
types. These pension funds’ investment policies target asset allocations from approximately 60% equity
securities and 40% fixed income securities in order to pursue a balance between moderate income generation and
capital appreciation.

Equity securities primarily include investments in large-cap and small-cap companies located in the U.S.
and international developed and emerging markets stocks. Fixed income securities are comprised of investment
and non-investment grade bonds, including U.S. Treasuries and U.S. and non-U.S. corporate bonds of companies
from diversified industries. Each pension fund investment policy allows a discretionary range in various asset
classes within the asset allocation model of up to 10%. The Company does not believe that there are significant
concentrations of risk in the pension plan assets due to its strategy of asset diversification. At December 31,
2021, plan assets did not include direct ownership of the Company’s common stock.

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.

The investments in the collective trust and mutual funds are valued using a market approach based on the

net asset value of units held. The fair values of the Company’s plan assets at December 31, by asset category, are

This category represents investment grade bonds of U.S. issuers, including U.S. Treasury notes.

The Company’s funding policy for its U.S. plans is consistent with the minimum funding requirements of

federal law and regulations, and based on preliminary estimates, the Company does not expect to make any
contributions to the pension plans in 2022.

Multi-employer Plans

Non-U.S. Plans

The Company participates in two multi-employer plans, Pensionskasse der Mitarbeiter der Hoechst-Gruppe
VVaG and Pensionskasse der Wacker-Chemie GmbH VVaG, which provide benefits to certain of the Company’s
employees in Germany. These multi-employer plans are closed to new participants. The benefit obligations are
covered up to a certain salary threshold by contributions made by the Company and employees to the plans.

Contributions to the Company’s multi-employer plans are expensed as incurred and were as follows:

The plan information for both the Pensionskasse der Mitarbeiter der Hoechst-Gruppe VVaG and
Pensionskasse der Wacker-Chemie GmbH VVaG plans is publicly available. The plans provide fixed,
monthly retirement payments on the basis of the credits earned by the participating employees. To the
extent that the plans are underfunded, future contributions to the plans may increase and may be used to
fund retirement benefits for employees related to other employers. The Company does not consider either
of its multi-employer plans individually significant.

Other Post-retirement Benefits

In the U.S., the Company provides post-retirement healthcare and life insurance benefits for certain
employees and their dependents who meet minimum age and service requirements. The Company has the right to
modify or terminate some of these benefits.

The Company also has a post-retirement plan in Canada which is unfunded and provides medical and life

insurance benefits for certain employees and their dependents.

15. Stock-Based Compensation

Under the Westlake Chemical Corporation 2013 Omnibus Incentive Plan (as amended and restated in 2017,

the “2013 Plan”), all employees and non-employee directors of the Company, as well as certain individuals who
have agreed to become the Company’s employees, are eligible for awards. Shares of common stock may be
issued as authorized in the 2013 Plan. At the discretion of the administrator of the 2013 Plan, employees and
non-employee directors may be granted awards in the form of stock options, stock appreciation rights, stock
awards, restricted stock units or cash awards (any of which may be a performance award). Outstanding stock
option awards have a 10-year term and vest (1) ratably on an annual basis over a three-year period or (2) at the
end of a five-year period. Outstanding restricted stock units and performance stock units vest either (1) ratably on
an annual basis over a two to five-year period or (2) at the end of a three or six-year period. In accordance with
accounting guidance related to share-based payments, stock-based compensation expense for all stock-based
compensation awards is based on estimated grant-date fair value. The Company recognizes these stock-based
compensation costs net of a forfeiture rate and on a straight-line basis over the requisite service period of the
award for only those shares expected to vest. For the years ended December 31, 2021, 2020 and 2019, the total
recognized stock-based compensation expense related to equity awards issued under the 2013 Plan was $31, $29
and $24, respectively.

The aggregate intrinsic value in the table above represents the total pretax intrinsic value (the difference

between the Company’s closing stock price on the last trading day of the year and the exercise price, multiplied
by the number of in-the-money options) that would have been received by the option holders had all option
holders exercised their options on December 31, 2021. This amount changes based on the fair market value of the
Company’s common stock. For the years ended December 31, 2021, 2020 and 2019, the total intrinsic value of
options exercised was $9, $11 and $1, respectively.

As of December 31, 2021, $7 of total unrecognized compensation cost related to stock options is expected
to be recognized over a weighted-average period of 1.7 years. Income tax benefits of $2, $2 and $0 were realized
from the exercise of stock options during the years ended December 31, 2021, 2020 and 2019, respectively.

16. Fair Value Measurements

The Company 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, all of
which are recorded at carrying value. The amounts reported in the consolidated balance sheets for cash and cash
equivalents, 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 Company’s long-term debt at December 31,
2021 and 2020 are summarized in the table below. The Company’s long-term debt instruments are publicly-
traded. A market approach, based upon quotes from financial reporting services, is used to measure the fair value
of the Company’s long-term debt. Because the Company’s long-term debt instruments may not be actively
traded, the inputs used to measure the fair value of the Company’s long-term debt are classified as Level 2 inputs
within the fair value hierarchy.

At December 31, 2021, the Company had federal, foreign and state net operating loss carryforwards
(“NOLs”) of approximately $22, $188 and $722, respectively. The federal NOL was acquired in connection with
the acquisition of Dimex. The federal NOL and certain foreign and state NOLs do not expire, while certain other
foreign and state NOLs expire in varying amounts between 2022 and 2041. The federal NOL and certain state
NOLs are subject to limitations on an annual basis. At December 31, 2021, the Company had various federal,
foreign and state credits carryforwards of $2, $2 and $19, respectively, which either do not expire or expire in
varying amounts between 2022 and 2036. Management believes the Company will realize the benefit of a portion
of the net operating loss carryforwards before they expire, but to the extent that the full benefit may not be
realized, a valuation allowance has been recorded. The valuation allowance decreased by $29 in 2021, primarily
due to the release in valuation allowance resulting from a change in management judgment regarding the
realizability of certain foreign deferred tax assets, including net operating loss carryforward, as a result of the
change in expectations of income in future years.

The Company has recognized a liability for uncertain income tax positions of $18 as of December 31,
2021. The Company does not believe it is likely that any material amounts will be paid in 2022. The ultimate
resolution and timing of payment for remaining matters continues to be uncertain.

The Company files income tax returns in the U.S. federal jurisdiction, various states and foreign

jurisdictions. The Company is no longer subject to examinations by tax authorities before the year 2014.

18. Earnings and Dividends per Share

The Company has unvested restricted stock units outstanding that are considered participating securities
and, therefore, computes basic and diluted earnings per share under the two-class method. Basic earnings per
share for the periods are based upon the weighted average number of shares of common stock outstanding during
the periods. Diluted earnings per share include the effects of certain stock options and performance stock units.

approximately $39, $34 and $32 for the years ended December 31, 2021, 2020 and 2019, respectively. The
Company also sold certain utilities to Air Liquide aggregating approximately $8, $7 and $7 during the years
ended December 31, 2021, 2020 and 2019, respectively. The amounts payable to Air Liquide were $3 and $3 at
December 31, 2021 and 2020, respectively, and the amounts receivable from Air Liquide were $1 and $1 at
December 31, 2021 and 2020, respectively.

21. Westlake Chemical Partners LP

In 2014, the Company formed Westlake Partners to operate, acquire and develop ethylene production
facilities and related assets. Also in 2014, Westlake Partners completed its initial public offering of 12,937,500
common units.

On March 29, 2019, Westlake Partners purchased an additional 4.5% newly issued limited partner interests

in OpCo for approximately $201 and completed a private placement of 2,940,818 common units at a price of
$21.40 per common unit for total proceeds of approximately $63. TTWF LP, the Company’s principal
stockholder and a related party, acquired 1,401,869 units out of the 2,940,818 common units issued in the private
placement. At December 31, 2021, Westlake Partners had a 22.8% limited partner interest in OpCo, and the
Company retained a 77.2% limited partner interest in OpCo and a significant interest in Westlake Partners
through the Company’s ownership of Westlake Partners’ general partner, 40.1% of the limited partner interests
(consisting of 14,122,230 common units) and incentive distribution rights.

On October 4, 2018, Westlake Partners and Westlake Partners GP, the general partner of Westlake
Partners, entered into an Equity Distribution Agreement with UBS Securities LLC, Barclays Capital Inc.,
Citigroup Global Markets Inc., Deutsche Bank Securities Inc., RBC Capital Markets, LLC, Merrill Lynch,
Pierce, Fenner & Smith Incorporated and Wells Fargo Securities, LLC to offer and sell Westlake Partners’
common units, from time to time, up to an aggregate offering amount of $50. This Equity Distribution
Agreement was amended on February 28, 2020 to reference a new shelf registration for utilization under this
agreement. No common units were issued under this program as of December 31, 2021.

22. Commitments and Contingencies

The Company is involved in a number of legal and regulatory matters, principally environmental in nature,

that are incidental to the normal conduct of its business, including lawsuits, investigations and claims. The

119

WESTLAKE CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(in millions of dollars, except share amounts and per share data)

outcome of these matters are inherently unpredictable. The Company believes that, in the aggregate, the outcome
of all known legal and regulatory matters will not have a material adverse effect on its consolidated financial
statements; however, under certain circumstances, if required to recognize costs in a specific period, when
combined with other factors, outcomes with respect to such matters may be material to the Company’s
consolidated statements of operations in such period. The Company’s assessment of the potential impact of
environmental matters, in particular, is subject to uncertainty due to the complex, ongoing and evolving process
of investigation and remediation of such environmental matters, and the potential for technological and
regulatory developments. In addition, the impact of evolving claims and programs, such as natural resource
damage claims, industrial site reuse initiatives and state remediation programs creates further uncertainty of the
ultimate resolution of these matters. The Company anticipates that the resolution of many legal and regulatory
matters, and in particular environmental matters, will occur over an extended period of time.

Antitrust Proceedings. The Company and other caustic soda producers were named as defendants in
multiple purported class action civil lawsuits filed since March 2019 in the U.S. District Court for the Western
District of New York. The lawsuits allege the defendants conspired to fix, raise, maintain and stabilize the price
of caustic soda, restrict domestic (U.S.) supply of caustic soda and allocate caustic soda customers. The other
defendants named in the lawsuits are Olin Corporation, K.A. Steel Chemicals (a wholly-owned subsidiary of
Olin), Occidental Petroleum Corporation, Occidental Chemical Corporation d/b/a OxyChem, Shin-Etsu Chemical
Co., Ltd., Shintech Incorporated, Formosa Plastics Corporation, and Formosa Plastics Corporation, U.S.A. Each
of the lawsuits is filed on behalf of the respective named plaintiff or plaintiffs and a putative class comprised of
either direct purchasers or indirect purchasers of caustic soda in the U.S. The plaintiffs seek an unspecified
amount of damages and injunctive relief. Three of the defendants, Occidental Petroleum Corporation, Shin-Etsu
Chemical Co., Ltd. and Formosa Plastics Corporation, were dismissed on jurisdictional or other grounds. The
other six defendants, including the Company, remain in the case. The defendants’ joint motion to dismiss the
direct purchaser lawsuits was denied and the cases have proceeded to discovery. Beginning in October 2020,
similar class action proceedings were also filed in Canada before the Superior Court of Quebec as well as before
the Federal Court. These proceedings seek the certification or authorization of a class action on behalf of all
residents of Canada who purchased caustic soda (including, in one of the cases, those who merely purchased
products containing caustic soda) from October 1, 2015 through the present or such date deemed appropriate by
the court. On December 10, 2021, the Superior Court of Québec stayed its proceedings, until after a final
certification decision is released in the Federal Court proceedings. At this time, the Company is not able to
estimate the impact, if any, that these lawsuits could have on the Company’s consolidated financial statements
either in the current period or in future periods.

Environmental. As of December 31, 2021 and 2020, the Company had reserves for environmental
contingencies totaling approximately $56 and $53, respectively, most of which was classified as noncurrent
liabilities. The Company’s assessment of the potential impact of these environmental contingencies is subject to
considerable uncertainty due to the complex, ongoing and evolving process of investigation and remediation, if
necessary, of such environmental contingencies, and the potential for technological and regulatory developments.

Calvert City Proceedings. For several years, the Environmental Protection Agency (the “EPA”) has been

conducting remedial investigation and feasibility studies at the Company’s Calvert City, Kentucky facility

120

WESTLAKE CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(in millions of dollars, except share amounts and per share data)

pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act of 1980
(“CERCLA”). As the current owner of the Calvert City facility, the Company was named by the EPA as a
potentially responsible party (“PRP”) along with Goodrich Corporation (“Goodrich”) and its
successor-in-interest, Avient Corporation (formerly known as PolyOne Corporation, “Avient”). On
November 30, 2017, the EPA published a draft Proposed Plan, incorporating by reference an August 2015 draft
Remedial Investigation (“RI”) report, an October 2017 draft Feasibility Study (“FS”) report and a Technical
Impracticability Waiver document dated December 19, 2017. On June 18, 2018, the EPA published an
amendment to its Proposed Plan. The amended Proposed Plan describes a final remedy for the onshore portion of
the site comprised of a containment wall, targeted treatment and supplemental hydraulic containment. The
amended Proposed Plan also describes an interim approach to address the contamination under the river that
would include recovery of any mobile contaminants by an extraction well along with further study of the extent
of the contamination and potential treatment options. The EPA’s estimated cost of implementation is $107, with
an estimated $1 to $3 in annual operation and maintenance (“O&M”) costs. In September 2018, the EPA
published the Record of Decision (“ROD”) for the site, formally selecting the preferred final and interim
remedies outlined in the amended Proposed Plan. In October 2018, the EPA issued Special Notice letters to the
PRPs for the remedial design phase of work under the ROD. In April 2019, the PRPs and the EPA entered into an
administrative settlement agreement and order on consent for remedial design. In October 2019, the PRPs
received special notice letters for the remedial action phase of work at the site. The Company, jointly with the
other PRPs, submitted a good faith offer response in December 2019. On September 17, 2020, the EPA and the
Department of Justice filed a proposed consent decree for the remedial action with the U.S. District Court for the
Western District of Kentucky. On November 16, 2020, the Department of Justice filed a motion to approve and
enter the consent decree. On January 28, 2021, the Court granted the unopposed motion to enter the consent
decree, which became effective the same day. The Company’s allocation of liability for remedial and O&M costs
at the Calvert City site, if any, is governed by a series of agreements between the Company, Goodrich and
Avient. These agreements and the associated litigation are described below.

In connection with the 1990 and 1997 acquisitions of the Goodrich chemical manufacturing complex in

Calvert City, Goodrich agreed to indemnify the Company for any liabilities related to preexisting contamination
at the complex. For its part, the Company agreed to indemnify Goodrich for post-closing contamination caused
by the Company’s operations. The soil and groundwater at the complex, which does not include the Company’s
nearby PVC facility, had been extensively contaminated by Goodrich’s operations. In 1993, Goodrich spun off
the predecessor of Avient, and that predecessor assumed Goodrich’s indemnification obligations relating to
preexisting contamination. In 2003, litigation arose among the Company, Goodrich and Avient with respect to
the allocation of the cost of remediating contamination at the site. The parties settled this litigation in December
2007 and the case was dismissed. In the settlement, the parties agreed that, among other things: (1) Avient would
pay 100% of the costs (with specified exceptions), net of recoveries or credits from third parties, incurred with
respect to environmental issues at the Calvert City site from August 1, 2007 forward; and (2) either the Company
or Avient might, from time to time in the future (but not more than once every five years), institute an arbitration
proceeding to adjust that percentage. In May 2017, Avient filed a demand for arbitration. In this proceeding,
Avient sought to readjust the percentage allocation of future costs and to recover approximately $11 from the
Company in reimbursement of previously paid remediation costs. The Company’s cross demand for arbitration

121

WESTLAKE CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(in millions of dollars, except share amounts and per share data)

seeking unreimbursed remediation costs incurred during the relevant period was dismissed from the proceedings
when Avient paid such costs in full at the beginning of the arbitration hearing.

On July 10, 2018, Avient sued the Company in the U.S. District Court for the Western District of Kentucky

and sought to invalidate the arbitration provisions in the parties’ 2007 settlement agreement and enjoin the
arbitration it had initiated in 2017. On July 30, 2018, the district court refused to enjoin the arbitration and, on
January 15, 2019, the court granted the Company’s motion to dismiss Avient’s suit. On February 13, 2019,
Avient appealed those decisions to the U.S. Court of Appeals for the Sixth Circuit. The court of appeals issued an
opinion and final order on September 6, 2019, affirming the district court.

The arbitration hearing began in August 2018 and concluded in December 2018. On May 22, 2019, the
arbitration panel issued its final award. It determined that Avient was responsible for 100% of the allocable costs
at issue in the proceeding and that Avient would remain responsible for 100% of the costs to operate the existing
groundwater remedy at the Calvert City site. In August 2019, Avient filed a motion to vacate before the U.S.
District Court for the Western District of Kentucky, seeking to invalidate the final award under the Federal
Arbitration Act. On February 11, 2020, the U.S. District Court for the Western District of Kentucky denied
Avient’s motion to vacate and affirmed the arbitration final award. Avient did not file a notice of appeal before
the March 10, 2020 deadline to contest the court’s decision. Accordingly, the final award was affirmed, and the
arbitration proceeding is fully and finally resolved.

At this time, the Company is not able to estimate the impact, if any, that any subsequent arbitration or
judicial proceeding could have on the Company’s consolidated financial statements either in the current period or
in later periods. Any cash expenditures that the Company might incur in the future with respect to the
remediation of contamination at the Calvert City complex would likely be spread out over an extended period. As
a result, the Company believes it is unlikely that any remediation costs allocable to it will be material in terms of
expenditures made in any individual reporting period.

Environmental Remediation: Reasonably Possible Matters. The Company’s assessment of the potential
impact of environmental contingencies is subject to considerable uncertainty due to the complex, ongoing and
evolving process of investigation and remediation, if necessary, of such environmental contingencies, and the
potential for technological and regulatory developments. As such, in addition to the amounts currently reserved,
the Company may be subject to reasonably possible loss contingencies related to environmental matters in the
range of $65 to $130.

Other Commitments

The Company has various unconditional purchase obligations, primarily to purchase goods and services,
including commitments to purchase various utilities, feedstock, nitrogen, oxygen, product storage and pipeline
usage. At December 31, 2021, unrecorded unconditional total purchase obligations were $5,079, which included
approximately $922 in 2022, $695 in 2023, $590 in 2024, $571 in 2025, $511 in 2026, and $1,790 thereafter.

23. Segment and Geographic Information

Segment Information

The Company has historically operated in two principal operating segments, Vinyls and Olefins. In
conjunction with the 2021 Acquisitions discussed in Note 2, and a resulting significant increase in the size of the
Company’s housing and infrastructure products operations, the Company reorganized its business into two
principal operating segments, Performance and Essential Materials and Housing and Infrastructure Products,
during the fourth quarter of 2021. These segments are strategic business units that offer a variety of different
materials and products. The Company manages each segment separately as each business requires different
technology and marketing strategies. These reporting changes have been retrospectively reflected in the segment
results for all periods presented.

The Company’s Performance and Essential Materials segment manufactures and markets polyethylene,
styrene monomer, ethylene co-products, PVC, VCM, ethylene dichloride (“EDC”), chlor-alkali (chlorine and
caustic soda), and chlorinated derivative products. The Company’s ethylene production is used in the Company’s
polyethylene, styrene and VCM operations. In addition, the Company sells ethylene and ethylene co-products,
primarily propylene, crude butadiene, pyrolysis gasoline and hydrogen, to external customers. The Company’s
primary North American manufacturing facilities are located in its Calvert City, Kentucky; Lake Charles,
Plaquemine and Geismar, Louisiana and Longview, Texas sites. The Company produces ethylene and
polyethylene at its facilities in Lake Charles, Louisiana; Calvert City, Kentucky and Longview, Texas. The
Company produces chlorine, caustic soda, VCM, EDC, PVC, hydrogen and chlorinated derivative materials at its
facilities in Lake Charles, Plaquemine and Geismar, Louisiana; Calvert City, Kentucky; Natrium, West Virginia;
Longview, Washington; Beauharnois, Quebec and Aberdeen, Mississippi. In addition to North America, the
Company also has manufacturing facilities in Europe and Asia.

No single customer accounted for more than 10% of sales in the Performance and Essential Materials

segment for the years ended December 31, 2021, 2020 or 2019.

The Housing and Infrastructure Products segment manufactures and markets products including residential

siding, trim and mouldings, stone, roofing, windows, outdoor living products, PVC pipe and fittings and PVC
compounds. As of December 31, 2021, the Company owned or leased 75 manufacturing facilities in North
America, Europe and Asia. The Company’s North American PVC facilities within the Performance and Essential
Materials segment supply most of the PVC required for the building products and pipes and fittings plants. The
raw materials for stone, roofing and accessories, windows, shutters and specialty tool products are externally
purchased. PVC required for the PVC compounds plants is either internally sourced from Company’s North
American or Asian facilities or externally purchased at market prices based on the location of the plants.

No single customer accounted for more than 10% of sales in the Housing and Infrastructure Products

segment for the years ended December 31, 2021, 2020 or 2019.

Item 9A. Controls and Procedures

Disclosure, 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 (our principal executive officer) and our Executive Vice
President and Chief Financial Officer (our principal financial officer), of the effectiveness of our disclosure
controls and procedures pursuant to Rules 13a-15 and 15d-15 under the Securities Exchange Act of 1934 as of
the end of the period covered by this Form 10-K. 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 as of December 31, 2021 to provide reasonable assurance that information required to be
disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized
and reported within the time periods specified in the SEC’s rules and forms, and is accumulated and
communicated to management as appropriate to allow timely decisions regarding required disclosure.

Internal Control Over Financial Reporting

Westlake’s management’s report on internal control over financial reporting appears on page 66 of this

Annual Report on Form 10-K. In addition, PricewaterhouseCoopers LLP, the independent registered public
accounting firm that audited the financial statements included in this Annual Report on Form 10-K, has also
audited the effectiveness of internal control over financial reporting as of December 31, 2021, as stated in their
report that appears on page 67 of this Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting

Except as described below, there were no changes in our internal control over financial reporting that

occurred during the quarter ended December 31, 2021 that have materially affected, or are reasonably likely to
materially affect, our internal control over financial reporting.

During the year ended December 31, 2021, we acquired the issued and outstanding equity interests of
certain subsidiaries of Boral Industries engaged in Boral’s North American building products businesses (“Boral
Target Companies”). We are in the process of integrating Boral North America into our overall internal control
over financial reporting process. Because we acquired Boral Target Companies during the current fiscal year, we
excluded Boral Target Companies from the scope of our assessment of the effectiveness of our internal control
over financial reporting as of December 31, 2021. This exclusion is in accordance with the general guidance
published by the Staff of the SEC that an assessment of a recent business combination may be omitted from
management’s report on internal control over financial reporting in the first year of consolidation. Boral Target
Companies’ total assets and total net sales represented 4.7% and 2.3% respectively, of the related consolidated
financial statement amounts as of and for the year ended December 31, 2021.
