Westlake Chemical Corporation Announces Fourth Quarter and Full Year 2015 Earnings

• Second highest annual earnings of $646.0 million in 2015

• Generated cash flow from operations in 2015 of $1,078.8 million

• Ended 2015 with cash and marketable securities of $1,182.7 million

Westlake Chemical Corporation (NYSE: WLK) today reported net income for the three months ended December 31, 2015 of $111.0 million, or $0.84 per diluted share, compared to net income of $183.3 million, or $1.37 per diluted share, reported for the fourth quarter of 2014. Net sales for the three months ended December 31, 2015 of $986.8 million decreased $149.1 million compared to net sales of $1,135.9 million in the same period of 2014, primarily due to lower sales prices for all of our major products, partially offset by higher sales volumes. Income from operations was $181.1 million in the fourth quarter of 2015 compared to $302.4 million for the fourth quarter of 2014. The decrease in income from operations was primarily the result of lower integrated Olefins and Vinyls margins, largely due to lower selling prices for all of our major products, partially offset by lower feedstock and energy costs and higher sales volumes. Income from operations for the fourth quarter of 2015 was negatively impacted by lower production rates, unabsorbed manufacturing costs and other costs associated with several polyethylene turnarounds.

Fourth quarter 2015 net income of $111.0 million, or $0.84 per diluted share, decreased by $72.6 million from the $183.6 million, or $1.39 per diluted share, reported in the third quarter of 2015. Net sales in the fourth quarter of 2015 of $986.8 million decreased $201.2 million from net sales of $1,188.0 million in the third quarter of 2015, mainly due to lower sales prices and volumes for all of our major products. Fourth quarter 2015 income from operations was $181.1 million as compared to $254.0 million for the third quarter of 2015, a decrease of $72.9 million. The decrease in operating income in the fourth quarter of 2015 as compared to the third quarter of 2015 was primarily the result of lower integrated product margins resulting from lower sales prices for our major products, partially offset by lower feedstock and energy costs. Net income for the third quarter of 2015 benefited from a lower effective tax rate resulting from several discrete items and other adjustments, partially offset by lost production and costs associated with turnaround activity.

For the year ended December 31, 2015, net income was $646.0 million, or $4.86 per diluted share, on net sales of $4,463.3 million. This represents a decrease in net income of $32.5 million, or $0.21 per diluted share, from 2014 net income of $678.5 million, or $5.07 per diluted share, on net sales of $4,415.4 million. Net income for the year ended December 31, 2015 benefited from a net pre-tax gain of $20.4 million, or $0.16 per diluted share, related to the bargain purchase gain from the acquisition of additional interest in our Huasu joint venture, net of related expenses, and a lower effective tax rate, primarily due to several discrete tax items and other adjustments, which collectively lowered the 2015 effective tax rate to 31.0% as compared to the 2015 effective tax rate on ordinary income of 33.6%. Net sales for the year ended December 31, 2015 increased $47.9 million to $4,463.3 million compared to net sales for 2014 of $4,415.4 million, primarily due to a full year of sales contributed by our specialty PVC resin business, Vinnolit, which we acquired on July 31, 2014, and higher sales volumes for most of our major products, partially offset by lower sales prices for all our major products. Income from operations was $959.8 million for the year ended December 31, 2015 as compared to $1,124.0 million for 2014. The decrease in 2015 income from operations as compared to 2014 was mainly attributable to lower olefins integrated product margins, primarily caused by lower sales prices and costs related to several turnarounds in 2015, partially offset by the contribution from Vinnolit for the full year 2015, increased production at our Calvert City, Kentucky facilities following the completion of the feedstock conversion and ethylene expansion project, higher production rates at our Geismar, Louisiana chlor-alkali plant and lower feedstock and

i

energy costs. Sales prices for the year ended December 31, 2015 were negatively impacted by the significant decline in crude oil prices.

"We are pleased to report strong earnings for 2015 for both our Olefins and Vinyls segments even with a precipitous decline in global crude oil prices, which resulted in lower selling prices for our major products," said Albert Chao, President and Chief Executive Officer. "In spite of this lower price environment in 2015, we benefited from strong demand for our polyethylene and PVC products as well as from the investments we have made to increase our ethylene and chlor-alkali capacities and from our acquisitions of Vinnolit and North American Specialty Products, expanding our product portfolio into specialty PVC resin and pipe."

EBITDA (earnings before interest expense, income taxes, depreciation and amortization) of $251.2 million for the fourth quarter of 2015 decreased by $104.1 million compared to EBITDA of $355.3 million in the fourth quarter of 2014. EBITDA for the fourth quarter of 2015 decreased by $66.7 million compared to EBITDA of $317.9 million in the third quarter of 2015. A reconciliation of EBITDA to reported net income and to net cash provided by operating activities can be found in the financial schedules at the end of this press release.

Net cash provided by operating activities was $1,078.8 million in 2015. Capital expenditures for 2015 were $491.4 million. As of December 31, 2015 we had cash and marketable securities of $1,182.7 million and our long-term debt was $764.1 million.

OLEFINS SEGMENT

The Olefins segment reported income from operations of $138.7 million in the fourth quarter of 2015, a decrease of $104.9 million compared to $243.6 million reported in the fourth quarter of 2014. This decrease was mainly attributable to lower olefins integrated product margins resulting from lower sales prices, partially offset by lower feedstock and energy costs, and higher sales volumes for polyethylene and styrene. In addition, income from operations in the fourth quarter of 2015 was negatively impacted by the costs and lost production associated with several polyethylene turnarounds.

The Olefins segment reported income from operations of $138.7 million for the fourth quarter of 2015, a decrease of $58.0 million from the $196.7 million reported in the third quarter of 2015. This decrease was primarily attributable to lower olefins integrated products margins primarily as a result of lower sales prices and lower sales volumes, partially offset by lower feedstock and energy costs. Additionally, fourth quarter 2015 results were negatively impacted by several polyethylene turnarounds.

The Olefins segment reported income from operations of $747.4 million in 2015 as compared to $1,013.8 million in 2014. This decrease was predominantly attributable to lower olefins integrated product margins, primarily as a result of lower sales prices, partially offset by higher sales volumes and lower feedstock and energy costs for the year ended December 31, 2015 as compared to 2014.

VINYLS SEGMENT

The Vinyls segment reported income from operations of $51.6 million in the fourth quarter of 2015 compared to income from operations of $66.3 million in the fourth quarter of 2014, a decrease of $14.7 million. This decrease was mainly attributable to lower sales prices for our major vinyls products, partially offset by higher sales volumes and lower feedstock and energy costs.

The Vinyls segment reported income from operations of $51.6 million in the fourth quarter of 2015, a decrease of $16.2 million compared to income from operations of $67.8 million in the third quarter of 2015. This decrease was mainly the result of lower sales volumes and lower sales prices for all of our major products, partially offset by lower feedstock and energy costs.

The Vinyls segment reported income from operations of $254.5 million in 2015 as compared to $142.7 million in 2014. This increase was primarily driven by higher vinyls integrated product margins for the year ended December 31, 2015, mainly attributable to the contribution from Vinnolit for the full year 2015, lower feedstock costs and increased production at our Calvert City facilities following the completion of the feedstock conversion and ethylene expansion project and higher caustic soda sales volume primarily attributable to higher production rates at our Geismar chlor-alkali plant, as compared to 2014. The increase in income from operations for the year ended December 31, 2015 was partially offset by lost sales, lower production rates and other costs associated with the turnarounds at our various North American and European facilities, lower sales prices for our major products and reduced sales volume in Europe related to an ethylene shortage. Income from operations for 2014 was negatively impacted by the lost sales, lower production rates and other costs associated with the turnaround at our Calvert City facilities.

The statements in this release and the related teleconference relating to matters that are not historical facts 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: general economic and business conditions; the cyclical nature of the chemical industry; availability, cost and volatility of raw materials and utilities, including natural gas 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; 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; 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, 2014, which was filed with the SEC in February 2015, and the risk factors in our other filings with the SEC.

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. 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 reported net income and to net cash provided by operating activities can be found in the financial schedules at the end of this press release.
