1Q 2023 Earnings Presentation
2 Westlake First Quarter 2023 Highlights Solid financial results reflecting sequential improvement against an uncertain macroeconomic backdrop: Net sales of $3.4 billion, an increase of 2% vs. fourth quarter 2022 net sales Net income of $394 million, an increase of 70% vs. fourth quarter 2022 net income EBITDA(1) of $825 million, an increase of 33% vs. fourth quarter 2022 EBITDA Volume increased 5% vs. fourth quarter 2022 due to increased seasonal construction activity Feedstock and energy costs fell in the U.S. and Europe on both a sequential and YoY basis Achieved approximately $25 million of cost savings in the first quarter towards our 2023 target of $55 - $105 million Strong balance sheet with $2.4 billion of cash and cash equivalents and $4.9 billion of gross debt locked in at interest rates averaging 3.2% with a weighted average maturity of more than 16 years 1) Reconciliation of EBITDA to Net Income, Income from Operations and Net Cash Provided by Operating Activities can be found on page 12
3 Westlake Corporation Performance First Quarter 2023 1) Net income attributable to Westlake 2) Reconciliations of EBITDA, Performance and Essential Materials EBITDA, Housing and Infrastructure Products EBITDA and Corporate EBITDA to the applicable GAAP measures can be found on pages 12 and 13 + Better global demand drove sequentially higher sales volume for most products with improved sales mix in PVC resin and polyethylene as sales volume shifted back to domestic from export markets + Lower natural gas, ethane and ethylene prices reduced feedstock and energy costs in both the U.S. and Europe + HIP segment EBITDA margin stable YoY at 20% despite a 21% volume decline due to higher average selling prices and lower raw material costs on both a sequential and YoY basis – Building and construction demand fell on a YoY basis driving lower HIP and PVC sales volumes and lower PVC average selling prices – Recent improvement in polyethylene and PVC prices weren’t enough to offset price reductions in the second half of 2022, driving lower average selling prices on both a sequential and YoY basis ($ in millions) 1Q 2023 4Q 2022 1Q 2023 vs. 4Q 2022 1Q 2022 1Q 2023 vs. 1Q 2022 Sales $3,356 $3,299 2% $4,056 (17%) Operating Income $536 $327 64% $1,032 (48%) Net Income(1) $394 $232 70% $756 (48%) Performance and Essential Materials EBITDA $615 $443 39% $1,071 (43%) Housing and Infrastructure Products EBITDA $205 $133 54% $258 (21%) Corporate EBITDA $5 $43 - ($29) - EBITDA(2) $825 $619 33% $1,300 (37%)

6 Performance and Essential Materials (“PEM”) Segment Performance + Improved global demand drove sequential volume growth + Sales volume shifted to domestic from export markets, improving sales mix and integrated margins sequentially + Feedstock and energy costs were lower on both a sequential and YoY basis in the U.S. and Europe + Epoxy sales volume and profitability benefited from the completion of the 4Q 2022 maintenance turnaround – Performance Materials average selling prices were lower on both a sequential and YoY basis across most product categories PEM Segment 1Q 2023 vs. 4Q 2022 Average Sales Price Volume -3.2% +2.7% PEM Segment 1Q 2023 vs. 1Q 2022 Average Sales Price Volume -12.9% -4.2% 1) Reconciliations of PEM EBITDA to the applicable GAAP measure can be found on page 13 2) PEM EBITDA margin is calculated by dividing PEM EBITDA by Total PEM Sales ($ in millions) 1Q 2023 4Q 2022 1Q 2023 vs. 4Q 2022 1Q 2022 1Q 2023 vs. 1Q 2022 Performance Materials Sales $1,282 $1,286 (0%) $1,929 (34%) Essential Materials Sales $1,067 $1,075 (1%) $903 18% Total PEM Sales $2,349 $2,361 (1%) $2,832 (17%) Operating Income $403 $219 84% $879 (54%) EBITDA(1) $615 $443 39% $1,071 (43%) EBITDA Margin(2) 26% 19% - 38% -
7 Lower natural gas and feedstock costs, on both a sequential and YoY basis, increased our structural North American cost advantage (~85% of production capacity) at a time of high global raw material and energy costs Customer demand improved from 4Q 2022 levels, which drove sequential volume improvement in 1Q 2023; however, volumes were below prior-year levels as customer orders reflected generally weaker end market demand Well positioned to benefit from secular demand driven by increasingly specialized products for housing, packaging, wind energy, aerospace and automotive Strong caustic soda prices driven by lower chlor-alkali operating rates due to globally lower PVC construction demand 1 2 3 4 Performance and Essential Materials Update
8 Housing and Infrastructure Products (“HIP”) Segment Performance 1) Reconciliations of HIP EBITDA to the applicable GAAP measure can be found on page 13 2) HIP EBITDA margin is calculated by dividing HIP EBITDA by Total HIP Sales + Stable EBITDA margin on a YoY basis despite a 21% volume decline demonstrates the stability that our HIP segment generates from its differentiated and branded products + Lower raw material costs on both a sequential and YoY basis + Sequentially higher volume across most products due to the seasonal increase in building and construction activity – Lower sales volume on a YoY basis due to weaker new construction activity as a result of higher mortgage rates – Sequentially lower average sales prices in some products HIP Segment 1Q 2023 vs. 4Q 2022 Average Sales Price Volume -2.3% +9.6% HIP Segment 1Q 2023 vs. 1Q 2022 Average Sales Price Volume +2.8% -20.6% ($ in millions) 1Q 2023 4Q 2022 1Q 2023 vs. 4Q 2022 1Q 2022 1Q 2023 vs. 1Q 2022 Housing Products Sales $818 $758 8% $972 (16%) Infrastructure Products Sales $189 $180 5% $252 (25%) Total HIP Sales $1,007 $938 7% $1,224 (18%) Operating Income $143 $68 110% $185 (23%) EBITDA(1) $205 $133 54% $258 (21%) EBITDA Margin(2) 20% 14% - 21% -
9 Repair & remodel (R&R) activity remained relatively stable, consistent with its lower historical volatility compared to new home construction Slowing new home construction as elevated mortgage rates drive affordability concerns Longer-term fundamentals for housing strength remain intact due to decade- plus of under-building, increasingly favorable demographics, and increasing popularity of remote work Infrastructure Investment and Jobs Act beginning to drive demand as states and municipalities start to develop construction projects to address our nation’s long neglected infrastructure needs 1 2 3 4 Housing and Infrastructure Products Update
