Pursuant to Rule 425 under the Securities Act of 1933 and Deemed Filed Pursuant to Rule 14a-12 under the Securities Exchange Act of 1934 Subject Company: Millennium Chemicals Inc. Commission File No. 1-12091 Date: May 5, 2004 Set forth below is the text of a news release issued by Millennium on May 5, 2004. This is being filed pursuant to Rule 425 under the Securities Act of 1933. Contact: Thomas Van Valkenburgh Manager of Investor Relations (410) 229-8113 FOR IMMEDIATE RELEASE --------------------- MILLENNIUM CHEMICALS POSTPONES CONFERENCE CALL AND -------------------------------------------------- PROVIDES INFORMATION ON FIRST QUARTER RESULTS --------------------------------------------- Hunt Valley, Maryland, May 5, 2004 -- Millennium Chemicals (NYSE-MCH) ("Millennium", or the "Company") announced today the postponement of its previously announced conference call on first quarter operating results and outlook scheduled for 1:00 p.m. on May 5, 2004. The postponement of the call and the issuance of first quarter operating results is necessary to provide Millennium with additional time to analyze the potential accounting ramifications in the first quarter of revised FASB Interpretation No. 46 (FIN 46), Consolidation of Variable Interest Entities, effective January 1, 2004 for variable interests acquired before February 1, 2003. FIN 46 is a highly technical accounting pronouncement that introduces an accounting model that under certain circumstances would require a company to consolidate another entity based on the sharing of economic risk and rewards rather than equity ownership and voting rights. The risk and rewards model of FIN 46 requires consolidation of that entity if the company participates in the majority of the entity's economics, whether or not those economics result from contractual arrangements, equity investments or other capital support. The following information is provided in lieu of the information normally included in the Company's quarterly earnings release on operating results. TITANIUM DIOXIDE The improved global economy has increased worldwide demand for our titanium dioxide products and has accelerated upward price momentum at the end of the first quarter of 2004. In US dollar terms, the average global first quarter price was similar to both last year's first quarter and the fourth quarter of 2003. However, average local currency selling prices in the first quarter of 2004 decreased 7 percent from last year's first quarter and decreased 3 percent from the fourth quarter of 2003. The first quarter 2004 TiO2 sales volume of 167,000 metric tons increased 15 percent from the first quarter of last year and increased 11 percent from the fourth quarter of 2003. Millennium estimates that the global TiO2 market increased 3 to 5 percent compared to the first quarter of 2003. Improved global economic conditions primarily account for the increased demand. The Company's TiO2 market share increased, which is consistent with the Company's objectives of offering leading market performance products and being price competitive in all markets to regain market share lost over the last few years. The first quarter 2004 TiO2 plant production operating rate was 93 percent of annual nameplate capacity of 690,000 metric tons compared to an operating rate of 88 percent in both last year's first quarter and the fourth quarter of 2003. Outlook We expect seasonally higher sales volume and improved local currency pricing for the Titanium Dioxide segment in the second quarter of 2004 as compared to the first quarter. The Company expects to realize higher selling prices as a result of implementing previous price announcements. Lower production volumes are expected in the second quarter due to the scheduling of planned maintenance activities. ACETYLS Higher prices and increased sales volume offset the high cost of natural gas during the first quarter of 2004, as compared in each case to the fourth quarter of 2003. In the aggregate, the weighted-average US dollar selling price for VAM and acetic acid in the first quarter of 2004 increased 4 percent from prices both in the first quarter of 2003 and the fourth quarter of 2003. Aggregate sales volume for VAM and acetic acid in the first quarter increased 8 percent from the first quarter of 2003 and increased 3 percent from the fourth quarter of 2003. Outlook Sales volume is expected to be similar to the first quarter of 2004 and local currency sales prices are expected to be slightly higher than the first quarter of 2004. In the second quarter of 2004, scheduled maintenance shutdowns will reduce production volumes. Additionally, future prices indicate higher second quarter costs for natural gas, our primary raw material. SPECIALTY CHEMICALS ------------------- The Specialty Chemicals segment is expected to return to profitability in the first quarter of 2004 driven primarily by higher sales volume. Sales volume increased 8 percent from the first quarter of 2003 and was 21 percent higher than the fourth quarter of 2003 due to seasonal demand. Average selling prices decreased 4 percent compared to both the first quarter of 2003 and the fourth quarter of 2003, primarily due to changes in product mix. Outlook Business conditions in the Specialty Chemicals segment in the second quarter of 2004 are expected to be similar to the first quarter of 2004. EQUISTAR CHEMICALS, LP Millennium's 29.5 percent stake in Equistar generated equity earnings on investment of $2 million in the first quarter of 2004 compared to an equity loss of $43 million in the first quarter of 2003 and $31 million equity loss in the fourth quarter of 2003. Improving economic conditions and tight supply/demand balances in several of Equistar's products contributed to improved results during the quarter. Compared to the first quarter of 2003, the first quarter of 2004 results improved significantly due to the average prices for ethylene and ethylene derivatives increasing by approximately 3 cents per pound. Equistar's combined ethylene and ethylene derivative sales volumes increased by approximately 5 percent. Compared to the fourth quarter of 2003, the first quarter of 2004 results improved significantly as ethylene and ethylene derivative (ethylene oxygenates and polyethylene) prices averaged 2 cents per pound to 3.5 cents per pound higher than during the fourth quarter. Price increases in Equistar products more than offset the impact of rising raw material costs, driven by average crude oil prices that were $4 per barrel higher in the first quarter of 2004 versus the fourth quarter of 2003. Significantly higher co-product (propylene, benzene, and fuels) prices more than offset the impact of an increase of approximately $100 million in crude-oil-based liquid raw material costs for all of Equistar. Ethylene and ethylene derivative volumes were relatively unchanged versus the fourth quarter of 2003. Outlook The level and volatility of crude oil and natural gas prices continue to negatively impact the industry, creating uncertainties for both near-term product margins and demand. Although Equistar continues to face raw material price uncertainties, improving industry conditions have enabled Equistar to deal with this volatility more successfully than during the past three years. If Equistar continues to experience solid global economic growth and some stabilization of energy prices, Equistar's business could enjoy very positive conditions later in the year. DEBT AND LIQUIDITY ------------------ During the first quarter of 2004, Millennium reduced net debt outstanding at December 31, 2003 by $34 million. During the first quarter the Company also repatriated cash of approximately $107 million from Australia and Europe to the US. This cash was used to reduce outstanding borrowings under the Company's Credit Agreement and for general corporate purposes. At the end of the first quarter of 2004, the Company had $21 million of outstanding undrawn letters of credit and no outstanding borrowings under the Credit Agreement and accordingly had $129 million of unused availability under this facility. COMBINATION UPDATE ------------------ As announced on March 29, 2004, Millennium executed a definitive agreement with Lyondell Chemical Company for a stock-for-stock business combination. The proposed business combination is subject to approval by both Millennium and Lyondell shareholders, the amendment of Millennium's and Lyondell's respective bank credit agreements and Lyondell's account receivable sales facility and other customary conditions. Millennium anticipates that the proposed business combination will occur during the third quarter of 2004. There can be no assurance that the proposed transaction will be completed.
