BUSINESS HIGHLIGHTS

In the first quarter of 2022, Westlake achieved record quarterly net sales of $4.1 billion, record quarterly net income of $756 million and record quarterly EBITDA of $1.3 billion. The Company benefitted from strong market conditions attributable to a robust demand environment.

i

In February 2022, the Company completed the acquisition of Hexion Inc.'s global epoxy business for approximately $1.2 billion in an all-cash transaction. Based in Rotterdam, The Netherlands, the epoxy business, branded as Westlake Epoxy, is a global industry leader in the manufacture and development of specialty resins, modifiers and curing agents for high-performance materials, coatings and composites utilized in a variety of industries, including high-growth and sustainability-oriented end-uses such as wind turbine blades and light-weight automotive structural components. The fully-integrated business includes upstream base epoxy resins and intermediates delivered as liquid or solid epoxy resins, as well as downstream specialty epoxy resins used in coatings and composites. Westlake Epoxy serves numerous industries, including marine and protective coatings, wind energy and general composites, civil engineering and construction, electrical laminates and electronics, automotive and aerospace as well as adhesives.

In the first quarter of 2022, the Company announced its target to reduce Scope 1 and Scope 2 CO2 equivalent emissions per ton of production by 20% by 2030 from a 2016 baseline. The Company has also expanded environmental reporting to better align with SASB industry standard and GRI framework. To further reduce its carbon footprint, Westlake's strategy is to optimally allocate capital to both proven and emerging technologies, including additional product and operational innovations. This strategy includes energy-efficiency projects, increasing power from less carbon-intensive electricity providers, adding more hydrogen as a fuel gas and other continuous operational improvements.

EXECUTIVE COMMENTARY

"The record results this quarter are driven by the groundwork Westlake has laid and the recent acquisitions that build on this solid foundation. The addition of our epoxy business to our PEM segment with its leading market position continues our drive toward a more differentiated and specialized product offering. Through the strong performance of all of our businesses and our recent acquisitions, we delivered record performance during the first quarter of 2022. I want to thank all of the Westlake employees for their hard work and dedication in helping us achieve these results. We continued to see robust residential construction and remodeling activity drive demand for PVC resin, as well as for products in our Housing and Infrastructure Products segment. The growth in the U.S. economy and the diminishing impact of COVID-19 continue to spur consumer and industrial demand with improvements in manufacturing and packaging benefiting caustic soda and polyethylene usage," said Albert Chao, President and Chief Executive Officer.

"While we see volatility driven by economic and geopolitical factors which could impact our businesses, market conditions currently remain favorable and we are confident in our business fundamentals and the markets in which we participate. We remain focused on our ESG tenets and continue to bring a portfolio of leading brands to market that not only enhance lives every day but also create a greener, more sustainable future for all of us, while also remaining steadfast in creating value for our shareholders. With the steps we have taken to date, combined with a continued strong demand outlook for our products, we remain optimistic about the future ahead," concluded Mr. Chao.

RESULTS

Consolidated Results

The Company reported record quarterly net income of $756 million (excluding a special tax benefit that occurred in the fourth quarter of 2017) on record net sales of $4,056 million for the three months ended March 31, 2022. Net income in the first quarter of 2021 was $242 million. The increase in net income of $514 million was driven by significantly higher sales prices and margins across most of our businesses as well as the contributions of the new businesses acquired in the second half of 2021 and early 2022. The continuing strength of residential construction driven by solid repair and remodeling markets drove strong demand and pricing dynamics for PVC resin as well as demand for a majority of offerings in the Housing and Infrastructure Products segment. Additionally, the Performance and Essential Materials segment experienced robust strength in polyethylene for packaging and consumer markets, epoxy coatings and applications, as well as caustic soda benefitting from increasing industrial activity, resulting in higher prices and margins. Despite rising feedstock costs and logistical constraints, margins expanded with pricing increases outpacing rising production costs.

Record EBITDA (earnings before interest expense, income taxes, depreciation and amortization) of $1,300 million for the first quarter of 2022 increased by $747 million compared to first quarter 2021 EBITDA of $553 million. A reconciliation of EBITDA to net income, income from operations, and net cash provided by operating activities can be found in the financial schedules at the end of this press release.

ii

Cash and Debt

Net cash provided by operating activities was $700 million for the first quarter of 2022. As of March 31, 2022, cash and cash equivalents were $1,055 million and total debt was $5,166 million. Westlake has given notice to redeem $250 million of debt on May 14, 2022. Capital expenditures were $263 million for the first quarter of 2022.

Performance and Essential Materials Segment

Performance and Essential Materials income from operations for the first quarter of 2022 of $879 million increased by $591 million from first quarter 2021 income from operations of $288 million. This increase in income from operations versus the prior-year period was due to strong demand dynamics from manufacturing, packaging and construction markets resulting in higher prices and margins for all major products in the segment. In addition, the first quarter of 2022 included income from operations from our recently acquired epoxy business.

Housing and Infrastructure Products Segment

For the first quarter of 2022, Housing and Infrastructure Products income from operations of $185 million increased by $114 million from first quarter 2021 income from operations of $71 million. This increase in income from operations versus the prior-year period was the result of continued robust housing construction and remodeling activity, driving healthy demand and higher prices across our businesses and the contributions of the acquisitions made in 2021. Despite rising raw material and energy costs as well as logistical constraints, margins expanded with pricing increases outpacing rising production costs.

Forward-Looking Statements

The statements in this release and the related teleconference relating to matters that are not historical facts, including statements regarding favorable market conditions, our outlook for our business segments, our ability to create value and grow, launching sustainable brands and reducing our carbon footprint, our planned redemption of outstanding debt, the contribution of recent acquisitions and demand for our products, are forward-looking statements. These forward-looking statements are subject to significant risks and uncertainties. Actual results could differ materially, based on factors including, but not limited to: the COVID-19 pandemic and the response thereto; general economic and business conditions; the cyclical nature of the industry; availability, cost and volatility of raw materials and utilities, including natural gas and natural gas liquids from shale production; the price of crude oil; uncertainties associated with the United States and worldwide economies, including those due to global economic and financial conditions; governmental regulatory actions, including environmental regulation and changes in trade policies; political unrest; industry production capacity and operating rates; the supply/demand balance for Westlake's products; competitive products and pricing pressures; access to capital markets; technological developments; the effect and results of litigation and settlements of litigation; operating interruptions; the ability to integrate the recent acquisitions; the diversion of management time on transaction-related issues; and other risk factors. For more detailed information about the factors that could cause actual results to differ materially, please refer to Westlake's Annual Report on Form 10-K for the year ended December 31, 2021, which was filed with the SEC in February 2022.

iii

Use of Non-GAAP Financial Measures

This release makes reference to certain "non-GAAP" financial measures, such as EBITDA, as defined in Regulation G of the U.S. Securities Exchange Act of 1934, as amended. For this purpose, a non-GAAP financial measure is generally defined by the Securities and Exchange Commission ("SEC") as a numerical measure of a registrant's historical or future financial performance, financial position or cash flows that (1) excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the most directly comparable measure calculated and presented in accordance with GAAP in the statement of income, balance sheet or statement of cash flows (or equivalent statements) of the registrant; or (2) includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the most directly comparable measure so calculated and presented. We report our financial results in accordance with U.S. generally accepted accounting principles ("U.S. GAAP"), but believe that certain non-GAAP financial measures, such as EBITDA, provide useful supplemental information to investors regarding the underlying business trends and performance of the Company's ongoing operations and are useful for period-over-period comparisons of such operations. These non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, the financial measures prepared in accordance with U.S. GAAP. A reconciliation of EBITDA to net income, income from operations and net cash provided by operating activities can be found in the financial schedules at the end of this press release.
