HOUSTON, Aug. 3 /PRNewswire-FirstCall/ -- Westlake Chemical Corporation (NYSE: WLK) today reported net income of $48.5 million, or $0.74 per diluted share, and income from operations of $82.8 million on net sales of $580.7 million for the second quarter of 2005. This compares favorably with second quarter 2004 net income of $34.4 million, or $0.69 per diluted share, and income from operations of $65.9 million on net sales of $449.4 million. The improvement in net sales and income from operations was primarily the result of increased sales volumes and increased selling prices, which outpaced higher feedstock and energy costs. PVC pipe sales volume increased driven by strong end-markets and by the August 2004 acquisition of the assets of Bristolpipe Corporation. Westlake Chemical uses the first-in, first-out (FIFO) method for valuing inventory. The FIFO method had a minimal negative impact on its second quarter results as compared with utilizing the last-in, first-out (LIFO) method used by some of our competitors.

Second quarter 2005 net income decreased $12.6 million, or $0.20 per diluted share from the $61.1 million net income, or $0.94 per diluted share, reported in the first quarter of 2005. Second quarter 2005 income from operations and net sales decreased $18.9 million and $37.9 million respectively, from the income from operations of $101.7 million and net sales of $618.6 million reported in the first quarter of 2005. These decreases were due primarily to lower selling prices for ethylene and polyethylene and higher raw material costs, which were partially offset by higher sales volumes in both segments and higher selling prices in our Vinyls segment.

Albert Chao, President and Chief Executive Officer, stated, "We are pleased to report another solid quarter as our results continue to significantly outpace the prior year. Although our Olefins segment results were below first quarter performance, we have seen positive signs in June and July of improved business activity, higher selling prices and reduced industry inventories."

For the six months ended June 30, 2005, net income was $109.7 million, or $1.68 per diluted share, on net sales of $1,199.3 million. This compares favorably with the six months ended June 30, 2004 net income of $45.1 million, or $0.91 per diluted share, on net sales of $850.3 million. Income from operations was $184.5 million for the six months ended June 30, 2005 as compared to $92.8 million for the six months ended June 30, 2004. These increases were primarily due to higher sales volumes in our Vinyls segment and higher selling prices for all of our olefins and vinyls products which outpaced higher feedstock and energy costs.

EBITDA (earnings before interest expense, income taxes, depreciation and amortization) for the second quarter of 2005 was $101.9 million compared to $85.5 million in the second quarter of 2004 and $122.9 million in the first quarter of 2005. A reconciliation of EBITDA to reported net income and to cash flow from operating activities can be found in the financial tables at the end of this press release.

The company generated strong cash flow from operations of $143.7 million in the first six months of 2005 and repaid $30.6 million of its senior secured notes during that period, leaving it with $109.7 million of cash and $267.5 million of debt on the balance sheet as of June 30, 2005.

OLEFINS SEGMENT

Income from operations for the Olefins segment decreased by $6.5 million to $32.0 million in the second quarter of 2005 from $38.5 million in the second quarter of 2004. This decrease was primarily due to higher raw material costs for ethane, propane and benzene, higher energy costs and lower sales volumes for ethylene and polyethylene, which were partially offset by higher selling prices and higher styrene sales volumes.

Second quarter 2005 income from operations for the Olefins segment decreased by $30.4 million from the $62.4 million income from operations reported in the first quarter of 2005. The decrease was primarily due to lower selling prices for ethylene and polyethylene, lower ethylene sales volumes and higher raw material and energy costs. These decreases were partially offset by higher styrene prices and higher polyethylene and styrene sales volumes.

Income from operations for the Olefins segment increased by $24.9 million to $94.4 million for the six months ended June 30, 2005 from $69.5 million for the six months ended June 30, 2004. This increase was primarily due to higher olefins selling prices, which outpaced higher raw material and energy costs. Sales volumes were relatively unchanged with slightly lower ethylene and polyethylene sales volumes essentially offset by higher styrene sales volumes. Merchant ethylene sales volumes were lower for the six months ended June 30, 2005 as compared to the six months ended June 30, 2004 due to the increase in internal ethylene consumption at the Geismar facility.

VINYLS SEGMENT

Income from operations for the Vinyls segment increased by $22.9 million to $51.0 million in the second quarter of 2005 from $28.1 million in the second quarter of 2004. This increase was primarily due to higher selling prices and higher sales volumes for all of the company's vinyls products. These increases were partially offset by higher energy and raw material costs.

Second quarter income from operations for the Vinyls segment increased by $9.3 million from the $41.7 million income from operations reported in the first quarter of 2005. The increase was primarily due to higher selling prices for caustic, PVC pipe and other PVC fabricated products and higher sales volumes for VCM and PVC pipe. These increases were partially offset by higher raw material costs.

Income from operations for the Vinyls segment increased by $67.8 million to $92.6 million for the six months ended June 30, 2005 from $24.8 million for the six months ended June 30, 2004. This increase was primarily due to higher selling prices and sales volumes for all of our vinyls products. These increases were partially offset by higher raw material and energy costs. The first six months of 2004 earnings were adversely impacted by a fire at the Calvert City ethylene plant. The estimated impact on operating income of the outage relating to the fire was approximately $8.4 million.

The statements in this release relating to matters that are not historical facts are forward-looking statements that are subject to risks and uncertainties. Actual results could differ materially, based on factors including, but not limited to: the cyclical nature of the chemical industry; availability, cost and volatility of raw materials and utilities; governmental regulatory actions and political unrest; global economic conditions; 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; 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, 2004, which was filed in March 2005.

In this release, Westlake refers to a non-GAAP financial measure, EBITDA. EBITDA is calculated as net income before interest expense, income taxes, depreciation and amortization. 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 to measure historical and future financial performance, financial position or cash flows, but excludes or includes amounts that would not be so adjusted in the most comparable GAAP measures. We have included EBITDA in this release 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. EBITDA allows for meaningful company-to-company performance comparisons by adjusting for factors such as interest expense, depreciation and amortization and taxes, which often vary from company to company. 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 earnings or of cash flow 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 in this release may not be comparable to EBITDA reported by other companies. EBITDA has material limitations as a performance measure because it excludes (1) interest expense, which is a necessary element of our costs and ability to generate revenues because we have borrowed money to finance our operations, (2) depreciation, which is a necessary element of our costs and ability to generate revenues because we use capital assets and (3) income taxes, which is a necessary element of our operations. We compensate for these limitations by relying primarily on our GAAP results and using EBITDA only supplementally. The following table reconciles EBITDA to net income and to cash flow from operating activities.
