<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>HOUSTON, July&nbsp;1, 2019</B> Westlake Chemical Corporation (NYSE: WLK), today announced net income, EBITDA, net sales and earnings per share guidance for
its second quarter 2019 and full-year financial results. Based on currently available information, Westlake expects that second quarter EBITDA will improve by approximately 8 to 15&nbsp;percent over results for the first quarter of 2019. Second
quarter 2019 net income is expected to be in the range of $106&nbsp;million to $123&nbsp;million, with EBITDA projected between $340&nbsp;million to $363&nbsp;million, on net sales of $2.1&nbsp;billion to $2.2&nbsp;billion, and diluted earnings
between $0.73 and $0.87 per share. For the full year 2019, Westlake expects net income to be in the range of $443&nbsp;million to $596&nbsp;million, with EBITDA projected between $1.4&nbsp;billion to $1.6&nbsp;billion, on net sales of
$8.0&nbsp;billion to $8.8&nbsp;billion, and diluted earnings between $3.10 and $4.28 per share based on current pricing and margin expectations for its products in the second quarter and full year 2019. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Westlake is providing this guidance on a <FONT STYLE="white-space:nowrap">one-time</FONT> basis given estimates from First Call have generally not been
updated as frequently as Westlake saw industry pricing and pricing expectations change during the second quarter. In the second quarter, while Westlake&#146;s average margin increased from the margin realized during the first quarter ended
March&nbsp;31, 2019, it did not increase as much as industry pricing expectations at the start of second quarter 2019 predicted. As Westlake has not started its second quarter 2019 financial close and related review procedures, the guidance set
forth is preliminary, subject to change, and is based upon information available as of the date of this press release. The guidance does not reflect events or transactions that may occur in the remainder of the full year 2019. In addition, during
the course of preparing its financial statements and their review, Westlake may identify items that would require it to make adjustments, which may be material to the amounts described. Westlake will provide final results for the second quarter in
its earnings release and earnings call, which is expected to take place on August&nbsp;6, 2019. See the end of this release for an explanation of Westlake&#146;s use of EBITDA and Table 1 for a reconciliation of EBITDA to net income. </P>

period-over-period comparisons of such operations. These <FONT STYLE="white-space:nowrap">non-GAAP</FONT> financial measures should be considered as a supplement to, and not as a substitute for, or superior to, the financial measures prepared in
