Tenneco Automotive Reports Third Quarter Results

Company Reduces Total Debt

-- Company reports net income of $3 million, or 9-cents per diluted share -- Original Equipment business improves gross margin performance -- Company lowers total debt by $93 million -- Working capital improvements generate $87 million in cash

LAKE FOREST, Ill., Oct. 21 -- Tenneco Automotive announced today that the company reported net income of $3 million, or 9-cents per diluted share, in the third quarter of 2003, versus net income of $5 million, or 13-cents per diluted share in the third quarter of 2002. The company generated $103 million in cash flow before financing activities, which reduced bank and bond debt to $1.404 billion. The company's strong cash performance in the quarter was primarily driven by $87 million in cash from working capital improvements, including reductions in receivables and inventory, and a 15 percent decrease in capital spending year-over-year.

"We are pleased with our performance in generating cash and continuing to pay down debt. We ended the quarter with borrowings under our revolving credit facility at zero and our bank and bond debt at the lowest level since becoming a stand-alone company," said Mark P. Frissora, chairman and CEO, Tenneco Automotive.

The company reported revenue of $915 million for the quarter versus $856 million in the third quarter 2002.

EBIT (earnings before interest, taxes, and minority interest) was $39 million in the quarter, down $1 million compared with third quarter 2002. EBIT before depreciation and amortization (EBITDA) was $79 million for the quarter, versus third quarter 2002 EBITDA of $75 million. See the table entitled, "Reconciliation of GAAP Results to non-GAAP Results," which is attachment 2 to the press release for more information about EBITDA and other non-GAAP results in this press release.

The third quarter 2003 results include pre-tax restructuring related expenses of $1 million, or 2-cents per diluted share, and a $3 million, or 9-cents per diluted share, tax benefit related to adjusting tax accounts to reflect the 2002 tax returns filed in the third quarter. In addition, the company reduced inventory balances by $17 million, primarily in the European aftermarket, which decreased the quarter's EBIT by $4 million. This EBIT decrease was the result of inventory absorption costs - fixed manufacturing costs that the company continued to incur in spite of the lower production levels necessary to drive inventory down. Because of the lower production levels, a greater portion of the fixed manufacturing costs were recognized in the income statement rather than allocated to inventory balances.

The third quarter 2002 results include pre-tax restructuring related expenses of $3 million, or 4-cents per diluted share, and a $2 million, or 6-cents per diluted share, tax benefit as a result of a change in the effective tax rate.

The company's total gross margin for the quarter was 20.5 percent versus 21.1 percent one year ago. Gross margin performance was negatively impacted by lower global aftermarket sales and the higher absorption costs associated with inventory reductions, which together more than offset improved gross margins in the company's original equipment business. Compared to one year ago, the gross margin for the European original equipment business improved nearly two percentage points and nearly one percentage point in the North American original equipment business.

The original equipment business gross margin improvement reflects cost savings generated by the company's focus on integrating its operations and improving manufacturing and distribution efficiency worldwide. In addition to Lean initiatives and global supply chain improvements, Six Sigma programs generated $6 million in savings during the quarter and Project Genesis, a global restructuring program, generated $5 million in incremental savings.

"We have a more variable cost structure in place to help offset some of the volume softness that we're seeing in our markets worldwide. However, we must continue to control costs and implement processes to improve our operating efficiency," said Frissora. "The global aftermarket continues to pull down our overall performance. We are continuing to adjust our manufacturing footprint and reduce capacity to help offset the tough market conditions. We are also pursuing opportunities to expand into new aftermarket product categories."

Tenneco Automotive again outperformed the requirements of its bank debt covenants. At September 30, the leverage ratio was 4.30, below the maximum limit of 5.25; the fixed charge coverage ratio was 1.47, exceeding the minimum required ratio of 0.95; and the interest coverage ratio was 2.55, exceeding the minimum required ratio of 1.80.

  NORTH AMERICA
  -- North American original equipment revenue was $329 million for the
     quarter versus $337 million in third quarter 2002.  Revenue was down
     2 percent, versus an estimated market decline of 5 percent.  Excluding
     the impact of lower pass-through catalytic converter sales, revenue was
     flat.
  -- North American aftermarket revenue was $123 million versus $129 million
     one year ago.  The decline was primarily due to a 9 percent decline in
     exhaust sales.
  -- EBIT for North American operations was $32 million compared with
     $36 million in the third quarter of 2002.  The EBIT decline was the
     result of lower volumes and higher marketing costs in the aftermarket
     business, which were partially offset by improved manufacturing
     efficiency in the original equipment operations.  Third quarter 2002
     EBIT included $1 million in restructuring related expenses.

  EUROPE
  -- European original equipment revenue increased to $253 million from
     $219 million in third quarter 2002.  Before the impact of favorable
     currency and pass-through catalytic converter sales, revenue was
     $167 million, versus third quarter 2002 revenue of $163 million
     excluding pass-through sales.  Significant year-over-year reductions in
     OE exhaust volumes impacted revenue and partially offset OE ride
     control volume increases on new platforms.
  -- European aftermarket revenue was $92 million compared with $86 million
     in third quarter 2002.  Excluding the impact of currency, revenue was
     $78 million.  The revenue decline was largely the result of a
     14 percent decline in aftermarket exhaust sales, adjusted for currency.
  -- European EBIT was a loss of $2 million compared with a loss of
     $1 million the previous year.  Favorable currency exchange rates
     benefited third quarter 2003 EBIT by $1 million.  The company's
     European original equipment business posted year-over-year earnings
     improvement.  However, absorption costs of $4 million for reducing
     inventories and restructuring related expenses of $1 million as well as
     the continuing aftermarket volume decline drove down overall earnings
     performance.  Earnings were also negatively impacted by higher
     depreciation costs of $5 million associated with the opening of a new
     facility in Eastern Europe and the appreciating Euro.  Third quarter
     2002 EBIT included $2 million in restructuring related expenses.

  REST OF WORLD
  -- The company's Australian operations increased revenue to $45 million
     from $31 million in third quarter 2002.  Excluding the favorable impact
     of currency, revenue was $36 million.  The increase was fueled by
     higher pass-through catalytic converter sales and strong volumes on
     existing platforms.
  -- Increased OE volumes in China and Thailand, including higher exhaust
     pass-through volumes in China, continue to drive revenue growth in
     Asia. Revenue from Asian operations was $42 million versus $30 million
     in third quarter 2002.
  -- In South America, the company reported revenue of $31 million, a
     31 percent increase over the third quarter 2002 revenue.  Excluding the
     impact of favorable currency exchange rates, revenue was up 22 percent.
  -- Combined EBIT for Asia, South America and Australia was $9 million in
     the third quarter 2003, compared with $5 million in the third quarter
     of 2002.  Higher revenue, favorable currency exchange rates and
     manufacturing efficiencies drove the improvement.

  (A) Generally Accepted Accounting Principles

  (B) Tenneco Automotive presents the above reconciliation of GAAP to non-
      GAAP results in order to reflect the results for the third quarters
      of 2003 and 2002 in a manner that allows a better understanding of
      the results of operational activities separate from the financial
      impact of decisions made for the long-term benefit of the company.
      Adjustments similar to the ones reflected above have been recorded in
      earlier periods, and similar types of adjustments can reasonably be
      expected to be recorded in future periods.  Using only the non-GAAP
      earnings measure to analyze earnings would have material limitations
      because its calculation is based on the subjective determinations of
      management regarding the nature and classification of events and
      circumstances that investors may find material.  Management
      compensates for these limitations by utilizing both GAAP and non-GAAP
      earnings measures reflected above to understand and analyze the
      results of the business.  The company believes investors find the
      non-GAAP information helpful in understanding the ongoing performance
      of operations separate from items  that may have a disproportionate
      positive or negative impact on the company's financial results in any
      particular period.

  (C) EBITDA represents net income before interest expense, income taxes,
      minority interest and depreciation and amortization.  EBITDA is not a
      calculation based upon generally accepted accounting principles.  The
      amounts included in the EBITDA calculation, however, are derived from
      amounts included in the historical statements of income data.  In
      addition, EBITDA should not be considered as an alternative to net
      income or operating income as an indicator of the company's operating
      performance, or as an alternative to operating cash flows as a measure
      of liquidity.  Tenneco Automotive has presented EBITDA because it
      regularly reviews EBITDA as a measure of the company's ability to
      incur and service debt.  In addition, Tenneco Automotive believes its
      debt holders utilize and analyze our EBITDA for similar purposes.
      Tenneco Automotive also believes EBITDA assists investors in comparing
      a company's performance on a consistent basis without regard to
      depreciation and amortization, which can vary significantly depending
      upon many factors.  However, the EBITDA measure presented may not
      always be comparable to similarly titled measures reported by other
      companies due to differences in the components of the calculation.

    Tenneco Automotive presents the above reconciliation of revenues in
    order to reflect the trend in the company's sales, in various product
    lines and geographical regions, separately from the effects of doing
    business in currencies other than the U.S. dollar.  Additionally,
    pass-through catalytic converter sales include precious metals pricing,
    which may be volatile.  While Tenneco Automotive's original equipment
    customers assume the risk of this volatility, it impacts reported
    revenue.  Excluding pass-through catalytic converter sales removes this
    impact.  Tenneco Automotive uses this information to analyze the trend
    in revenues before these factors. Tenneco Automotive believes investors
    find this information useful in understanding period to period
    comparisons in the company's revenues.
