HOUSTON, April 27 /PRNewswire-FirstCall/ -- Lyondell Chemical Company (NYSE: LYO) today announced net income for the first quarter 2006 of $290 million, or $1.12 per share on a fully diluted basis. This compares with net income of $254 million, or 98 cents per share, for the first quarter 2005, and net income of $141 million, or 54 cents per share, for the fourth quarter 2005.

First-quarter results, excluding a settlement related to Lyondell-Citgo Refining (LCR), were comparable to the first quarter 2005, as improved refining and propylene oxide (PO) segment results and lower interest expense offset a decline in ethylene segment results. Improvement versus the fourth quarter 2005 is primarily attributed to strong results in the refining segment versus the hurricane-damage related downtime experienced in the fourth quarter 2005.

   Quarterly results reflected the following:

"Business results have been solid thus far in 2006, and we are pleased to have resolved several open issues in our favor. First-quarter 2006 earnings were strong, and we continued to improve our balance sheet through the repayment of $437 million principal amount of debt," said Dan F. Smith, president and CEO of Lyondell Chemical Company. "Unfortunately, during the quarter we believe the market overreacted to the verdict in the Rhode Island lead pigment trial. This matter is far from concluded, and we expect the financial impact, if any, will be far less than the initial reaction would indicate."

OUTLOOK

The ethylene chain has largely adjusted to resumed production following planned and unplanned outages in the industry. While this is resulting in lower product prices in the ethylene chain, profitability over the course of the year is expected to reflect industry operating rates in the mid-90 percentiles. As the summer driving season begins, conditions for the refining industry are expected to remain very tight. Despite this, U.S. refiners are removing methyl tertiary butyl ether (MTBE) from their systems, and Lyondell has shifted its MTBE sales mix to reflect this situation by emphasizing exports from the United States. Globally, MTBE margins have followed typical seasonal trends thus far in 2006.

"Volatility and current high prices in the energy markets continue to present challenges, but strong business conditions ultimately should prevail, positioning Lyondell's chemical products for another strong year," added Smith. "Tightness in the refining industry creates an opportune situation for the sale of the LCR refinery at a time that should maximize its value and allow us to accelerate and expand our already successful debt-reduction efforts."

In April 2006, Lyondell was granted an arbitration award related to a commercial dispute with Bayer. The award was not reflected in first-quarter earnings. It pertains to several issues related to the companies' U.S. PO and PO technology joint ventures and included declaratory judgment in Lyondell's favor concerning interpretation of the contract provisions at issue. Lyondell was awarded approximately $121 million, plus interest of approximately $23 million, through June 30, 2005. Additional amounts subject to finalization could include pre-award and post-award interest and attorney fees, costs and expenses.

LYONDELL BUSINESS RESULTS DISCUSSION BY REPORTING SEGMENT

Lyondell operates in four segments: 1) Ethylene, co-products and derivatives; 2) PO and related products; 3) Inorganic chemicals; and 4) Refining, which includes Lyondell's 58.75 percent ownership of LCR, a joint venture with CITGO Petroleum Corp.

Ethylene, Co-products and Derivatives Segment -- The primary products of this segment are ethylene, ethylene co-products (propylene, butadiene and benzene), and derivatives of ethylene (polyethylene, ethylene oxygenates and vinyl acetate monomer or VAM).

       Lyondell.

1Q06 v. 4Q05 -- Ethylene and ethylene derivative product sales volumes increased by approximately 70 million pounds (3 percent) versus the fourth quarter 2005. Quarterly average prices for ethylene and polyethylene decreased by 9 cents and 4 cents per pound, respectively, compared with the fourth quarter 2005. The company's cost-of-ethylene-production metric (COE) decreased by approximately 3 cents per pound versus the fourth quarter. Essentially all of this decrease is attributed to the lower price of natural-gas-based raw materials. Acetyls results improved by approximately $10 million, as margins increased due to lower raw material (natural gas and ethylene) costs.

1Q06 v. 1Q05 -- Ethylene and ethylene derivative product sales volumes were relatively unchanged versus the first quarter 2005. The quarterly average prices for ethylene and polyethylene increased by 6 cents and 8 cents per pound, respectively, while the average ethylene glycol price decreased by approximately 5 cents per pound compared with the first quarter 2005. The company's COE metric increased by approximately 8 cents per pound as the cost of production from both crude oil- and natural-gas-based raw materials increased. Elevated raw material costs in the first quarter 2006 resulted in a $20 million decline in acetyls results.

PO and Related Products Segment -- The principal products of the PO and related products segment include PO, PO derivatives (propylene glycol, propylene glycol ethers, butanediol and butanediol derivatives), styrene, MTBE and toluene diisocyanate (TDI).

   Table 3 - PO & Related Products Financial Overview (A)

  Millions of dollars                      1Q 2006      1Q 2005    4Q 2005
  Sales and other operating revenues        $1,644       $1,523     $1,645
  Operating income                             117           89         35

   (A) See Table 6 for additional segment information.
   (B) See Table 9 for a reconciliation of segment EBITDA to net income of
       Lyondell.

1Q06 v. 4Q05 -- TDI results improved by approximately $40 million due to the absence of costs related to the shutdown of the Lake Charles TDI facility and higher margins. PO results improved by approximately $35 million primarily due to stronger margins. Styrene and MTBE results were relatively unchanged.

1Q06 v. 1Q05 -- Versus the year-ago quarter, results improved by approximately $29 million primarily due to moderately stronger results in TDI, PO and PO derivatives, and MTBE. PO and PO derivative volumes declined primarily due to lower aircraft deicer sales volumes related to the warm winter weather compared with first quarter 2005.

Inorganic Chemicals Segment -- The principal product of the inorganic chemicals segment is titanium dioxide (TiO2).

  Millions of dollars                      1Q 2006      1Q 2005    4Q 2005

   (A) See Table 6 for additional segment information.
   (B) See Table 9 for a reconciliation of segment EBITDA to net income of
       Lyondell.

1Q06 v. 4Q05 -- A decline in sales volumes of approximately 11,000 metric tons versus the fourth quarter 2005 was largely offset by an increase in the average sales price (in U.S. dollars) of approximately $50 per metric ton. Strong operations and lower natural gas costs resulted in a $20 million decline in production costs.

1Q06 v. 1Q05 -- Sales volumes were approximately 9,000 metric tons higher than the year-ago quarter, while average sales prices were approximately $20 per metric ton higher. North and South American price increases were partially offset by lower European prices. Production costs increased compared with the first quarter 2005 due to higher raw material and natural gas costs.

Refining Segment -- Lyondell owns a 58.75 percent interest in LCR, a major refiner of heavy crude oil. This interest is accounted for by the equity method.

  Millions of dollars                      1Q 2006      1Q 2005    4Q 2005

       expenses paid by Lyondell on behalf of LCR related to the settlement.
   (C) See Table 9 for a reconciliation of segment EBITDA to net income of
       LCR.

1Q06 v. 4Q05 -- Refinery crude processing rates increased by approximately 92,000 barrels per day versus the fourth quarter 2005, which was impacted by hurricane damage-related fluid catalytic cracking unit downtime. The total crude processing rate averaged 261,000 barrels per day while Venezuelan contract (CSA) crude volumes averaged 221,000 barrels per day during first quarter 2006. Increased spot crude volumes more than offset a reduction in spot crude margins. The refinery also benefited from lower natural gas costs and strong operations during the first quarter 2006.

1Q06 v. 1Q05 -- Versus the first quarter 2005, operating efficiencies, premium product production and higher margins (CSA and spot crude) more than offset increased natural gas costs and lower aromatic margins. Total crude volumes were relatively unchanged.

Cash Distributions and Debt Reduction

LCR to Lyondell Chemical Company -- During the first quarter 2006, LCR made a net distribution of $46 million to Lyondell Chemical Company.

Equistar to Lyondell Chemical Company and Millennium -- During the first quarter 2006, Lyondell Chemical Company received $141 million of distributions from Equistar. Millennium received $59 million from Equistar during the first quarter 2006.

Millennium to Lyondell Chemical Company -- There were no dividends paid by Millennium to Lyondell Chemical Company during the first quarter 2006.

Debt reduction -- During the first quarter 2006, Lyondell repaid $437 million principal amount of debt, of which $237 million was Millennium debt, $150 million was Equistar debt and the $50 million balance was Lyondell parent company debt.
