1 EXHIBIT 99.1 TENNECO SHAREOWNERS APPROVE REVERSE STOCK SPLIT AND DECLASSIFIED BOARD FOR TENNECO AUTOMOTIVE GREENWICH, Conn., Oct. 25, 1999 -- Tenneco Inc. (NYSE: TEN) said today that the company's shareowners have approved proposals providing for the annual election of directors of the continuing Tenneco entity, Tenneco Automotive, after the spin-off of Tenneco Packaging, and to effect upon the spin-off a one- for-five reverse stock split of the automotive company's common stock. The first of two proposed amendments, which eliminates over a three-year period the current classification of the company's board of directors, was approved by the majority of the company's shareowners entitled to vote on the matter. It will phase out the current division of the board of directors into three classes, with one class elected each year for a three-year term, and provide instead for the annual election of directors commencing with the class of directors standing for election at the next annual meeting of shareowners. The second amendment, the reverse stock split, which will not change a shareowner's proportionate equity interest in the company except from the disposition of any fractional shares, also was approved by the majority of the company's shareowners entitled to vote on the matter. The reverse stock split also will only take effect when the spin-off is completed. The planned tax-free spin-off of Tenneco Packaging to shareowners and the separation of Tenneco Automotive and Tenneco Packaging is scheduled for Nov. 4. As the planned spin-off and separation of the two companies proceeds, the company anticipates several further key events occurring. Trading in Tenneco Packaging and Tenneco Automotive (to give effect to the reverse stock split) is expected to begin on the New York Stock Exchange on a "when issued" basis Oct. 27. Completion of the tender offers and exchange offers in order to realign Tenneco's debt is expected to occur Nov. 3. The tax-free spin-off of Tenneco Packaging to shareowners of record Oct. 29 is expected to occur after close of business Thursday, Nov. 4, and the two separate businesses are expected to begin regular trading as stand-alone companies Friday, Nov. 5.
