Tenneco Reports Strong Second Quarter Results

- Net income up 67%, EPS up 65% year-over-year

- EBIT up 39%; EBITDA up 26% year-over-year

- Record high quarterly revenue of $1.7 billion

LAKE FOREST, Ill., July 26, 2007 -- Tenneco reported second quarter 2007 net income of $40 million, or 84-cents per diluted share, a significant increase from $24 million, or 51-cents per diluted share in second quarter 2006. Adjusted for the items below, net income was $41 million, or 87-cents per diluted share, versus $33 million, or 71-cents per diluted share one year ago (the tables attached to the press release reconcile GAAP results to non-GAAP results). The comparative 2006 financial results reflect the preliminary results of the restatement discussed in the company's July 23, 2007 press release. Final 2006 results will be reflected in Tenneco's restated financial statements that it expects to file in August 2007.

EBIT (earnings before interest, taxes and minority interest) increased to $102 million, from $74 million a year ago. Adjusted EBIT was $104 million, compared with $88 million in second quarter 2006. Growth in global sales on OE platforms featuring advanced technology content and operational efficiencies drove the year-over-year profit improvement.

EBITDA (EBIT before depreciation and amortization) was $152 million, up from $121 million and adjusted EBITDA rose to $154 million from $135 million for the same period last year.

Second quarter revenue increased 36% to $1.7 billion versus $1.2 billion a year ago. Substrate sales were $460 million, up from $213 million in second quarter 2006. Excluding substrate sales and favorable currency of $49 million, revenue was up 16% to $1.16 billion from $1.0 billion. The revenue growth was driven by volume increases on large North American OE emission control platforms as well as continued revenue growth in the European OE businesses and in expanding markets like China.

   Second quarter 2007 adjustments:
   --   Restructuring and restructuring related expense of $2 million pre-
        tax, or 3-cents per diluted share.
   Second quarter 2006 adjustments:
   --   Restructuring and restructuring related expenses of $8 million pre-

   --   Aftermarket customer changeover costs of $6 million pre-tax, or 8-
        cents per diluted share.

"We are very pleased with our results this quarter. In North America, the ramp-up and execution on our large diesel aftertreatment truck business is reaching the production levels we had anticipated," said Gregg Sherrill, chairman and CEO, Tenneco. "In addition, we saw robust performance in Europe and China, which reflects Tenneco's strong geographic position."

Gross margin in the quarter was 17.2% versus 20.5% in second quarter 2006. The decline was driven by substantially higher substrate sales, primarily from volume increases on diesel truck platforms in North America, lower OE ride control sales for commercial vehicles due to the significant production decline in that industry, and a shift toward a lower percentage of total revenue generated by higher margin aftermarket business.

Total steel costs in the quarter increased $18 million year-over-year. The company offset these increases with cost reductions, material substitutions, low cost country sourcing and steel price recovery efforts with aftermarket and OE customers. The company has completed nearly all its customer steel recovery negotiations.

SGA&E (selling, general, administrative & engineering) expenses as a percent of sales decreased to 8.1% from 10.5% at the end of second quarter 2006. The company held overhead costs flat while increasing revenues and continuing to invest in engineering and technology development for its OE emission control and ride control businesses globally.

EBIT as a percent of revenue in the quarter was up year-over-year. The margin benefit from advanced technology content on new large-volume OE platform launches, cost reduction efforts and an improvement in SGA&E as a percent of sales offset the unfavorable margin impact of higher substrate sales and the shift to a higher percentage of OE revenues.

Interest expense in the quarter was $40 million, up from $35 million a year ago. The requirement to mark Tenneco fixed to floating interest rate swaps to market increased interest expense by $3 million in second quarter 2007, versus an increased expense of $2 million in the second quarter 2006. A higher level of borrowings in the quarter drove the remainder of the interest expense increase.

Cash provided by operating activities was an inflow of $67 million, versus $73 million in second quarter 2006. Cash used for working capital was $14 million versus $10 million a year ago despite higher revenues in second quarter 2007.

At quarter-end, debt net of cash balances was $1.282 billion, compared with $1.256 billion a year ago. Total debt was $1.450 billion versus $1.379 billion at the end of second quarter 2006, driven by working capital investments to service a higher level of revenues. At quarter-end, the ratio of debt net of cash balances to adjusted LTM (last twelve months) EBITDA was 2.9x, improved from 3.0x a year ago.

   NORTH AMERICA
   --   North America OE revenue increased 80% to $661 million from $367
        million a year ago.  Industry production was down 3% in the quarter.
        Excluding substrate sales, revenue was $395 million, up 29% year-
        over-year from $306 million.  Higher volumes on the Toyota Tundra,
        GM cross-over vehicles and the ramp-up on significant new diesel
        emission control platforms including the Ford Super-Duty, the GM
        Duramax engines, the Dodge heavy-duty Ram and International's
        medium-duty diesel trucks drove the increase.
   --   North America aftermarket revenue was down 5% to $149 million from
        $156 million a year ago.  Softer market conditions for both ride and
        emission control products were partially offset by price increases
        to recover steel costs.
   --   EBIT for North American operations was $49 million, versus $37
        million a year ago.  Adjusted for the items below, EBIT was $49
        million, versus $47 million in second quarter 2006.  Strong OE
        emission control volumes and manufacturing efficiencies,
        particularly the efficient ramp-up on key emission control truck
        platforms, offset lower aftermarket volumes and higher material
        costs.
   --   Second quarter 2006 EBIT includes $4 million in restructuring and $6
        million for customer changeover costs.

   EUROPE, SOUTH AMERICA AND INDIA
   --   Europe OE revenue was $513 million, up 25% from $412 million in
        second quarter 2006.  Industry production increased 4% in the
        quarter.  Excluding $29 million in favorable currency and higher
        substrate sales, revenue was $347 million, up 18% compared with $292
        million a year ago.  The increase was largely driven by increased
        volumes on emission control platforms and new ride control model
        launches.
   --   Europe aftermarket revenue increased 5% to $124 million from $118
        million the previous year.  Excluding favorable currency, revenue
        was relatively flat year-over-year.  Stronger ride control volumes
        were offset by lower emission control product sales.
   --   South America and India revenue increased to $81 million from $66
        million the previous year, driven by favorable currency and stronger
        volumes in South America.  Excluding currency and substrate sales,
        revenue was $65 million, versus $58 million a year ago, an increase
        of 12%.
   --   EBIT for Europe, South America and India increased 29% to $45
        million, versus $35 million a year ago.   Stronger OE volumes and
        operating efficiency improvements more than offset the impact of
        higher material costs.  Favorable currency had a $3 million impact
        on EBIT.  Adjusted for the items below, EBIT was $47 million, versus
        $38 million in second quarter 2006.
   --   Second quarter 2007 EBIT includes $2 million in restructuring costs
        and second quarter 2006 EBIT includes $3 million in restructuring
        costs.

   ASIA PACIFIC
   --   Asia revenue was up 48% to $85 million, compared with $58 million a
        year ago.  Excluding substrate sales, Asia revenue was up 43% to $55
        million from $39 million a year ago.  The China operations drove the
        increase with strong OE volumes and a 57% year-over-year revenue
        gain.
   --   Australia revenue increased 14% to $50 million from $44 million in
        second quarter 2006.  Excluding favorable currency and substrate
        sales, revenue was $37 million, down from $39 million a year ago.
   --   Asia Pacific EBIT was $8 million, up from $2 million in second
        quarter 2006, driven by OE volume growth in China.  Excluding the
        items below, EBIT increased 146%.
   --   Second quarter 2006 EBIT includes $1 million in restructuring costs.

  OUTLOOK

Industry predictions indicate stronger year-over-year OE production in North America through the remainder of the year and Tenneco is well-positioned to benefit with its new diesel pick-up truck platforms and a good position on strong-selling cross-over vehicles. However, the company will continue to closely monitor market uncertainties, namely rising inventory levels and labor negotiations in North America.

The company also expects its strong performance will continue in Europe and in emerging markets like China, where industry conditions are expected to remain positive. In the aftermarket, the company continues to support its strong brands and aggressively pursue new customers, actions that it hopes will counter any continued softness in the European and North American markets.

Tenneco will continue to invest in engineering and new technologies, primarily to develop next generation emissions and ride control products. The company's diesel aftertreatment capabilities and innovative hot-end emission control solutions are generating new business opportunities and positioning Tenneco for future growth.

"The next five years offer significant opportunities for Tenneco as emissions standards tighten in key markets worldwide. We are staying focused on using our technology and global footprint to capture this new business," said Sherrill. "Equally important, we are working to continue growing profitably, keeping a sharp eye on costs and continuously improving our manufacturing efficiency."

This press release contains forward-looking statements. Words such as "hopes," "may," "expects," "anticipate," "will," and "outlook" and similar expressions identify forward-looking statements. These forward-looking statements are based on the current expectations of the company (including its subsidiaries). Because these forward-looking statements involve risks and uncertainties, the company's plans, actions and actual results could differ materially. Among the factors that could cause these plans, actions and results to differ materially from current expectations are:

(i) changes in automotive manufacturers' production rates and their actual and forecasted requirements for the company's products;

(ii) the overall highly competitive nature of the automotive parts industry, including pricing pressure from the company's OE customers and the loss of any awards of business, or the failure to obtain new awards of business, from our large customers, on which we are dependent for a substantial portion of our revenues; for example, Ford, from whom the company derived more than 10% of its 2006 net sales, announced in 2006 a plan to significantly reduce the number of its global suppliers. While the company currently believes that its relationship with Ford will not be impacted by this plan, any significant reduction in sales to Ford could have a material adverse effect on the company;

(iii) the company's resultant inability to realize the sales represented by its awarded book of business which is based on anticipated pricing for the applicable program over its life, and is subject to increases or decreases due to changes in customer requirements, customer and consumer preferences, and the number of vehicles actually produced by customers;

(iv) increases in the costs of raw materials, including the company's ability to successfully reduce the impact of any such cost increases through materials substitutions, cost reduction initiatives, customer recovery and other methods;

(v) the cyclical nature of the global vehicular industry, including the performance of the global aftermarket sector, and changes in consumer demand and prices, including longer product lives of automobile parts and the cyclicality of automotive production and sales of automobiles which include the company's products, and the potential negative impact on the company's revenues and margins from such products;

(vi) the company's continued success in cost reduction and cash management programs and its ability to execute restructuring and other cost reduction plans and to realize anticipated benefits from these plans;

(vii) the general political, economic and competitive conditions in markets and countries where the company and its subsidiaries operate, including the strength of other currencies relative to the U.S. dollar and currency fluctuations and other risks associated with operating in foreign countries;

(viii) governmental actions, including the ability to receive regulatory approvals and the timing of such approvals;

(ix) changes in capital availability or costs, including increases in the company's costs of borrowing (i.e., interest rate increases), the amount of the company's debt, the ability of the company to access capital markets and the credit ratings of the company's debt;

(x) the cost and outcome of existing and any future legal proceedings, and compliance with changes in regulations, including environmental regulations;

(xi) workforce factors such as strikes or labor interruptions;

(xii) the company's ability to develop and profitably commercialize new products and technologies, and the acceptance of such new products and technologies by the company's customers and the market;

(xiii) further changes in the distribution channels for the company's aftermarket products, further consolidations among automotive parts customers and suppliers, and product warranty costs;

(xiv) changes by the Financial Accounting Standards Board or other accounting regulatory bodies to authoritative generally accepted accounting principles or policies;

(xv) acts of war, riots or terrorism, including, but not limited to the events taking place in the Middle East, the current military action in Iraq and the continuing war on terrorism, as well as actions taken or to be taken by the United States or other governments as a result of further acts or threats of terrorism, and the impact of these acts on economic, financial and social conditions in the countries where the company operates; and

(xvi) the timing and occurrence (or non-occurrence) of transactions and events which may be subject to circumstances beyond the control of the company and its subsidiaries.

The company undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date of this press release. Additional information regarding these risk factors and uncertainties is detailed from time to time in the company's SEC filings, including but not limited to its report on Form 10-K for the year ended December 31, 2006.

  (1) Generally Accepted Accounting Principles

(2) EBITDA represents 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 has presented EBITDA because it regularly reviews EBITDA as a measure of the company's performance. In addition, Tenneco believes its debt holders utilize and analyze our EBITDA for similar purposes. Tenneco 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.

  (1) Generally Accepted Accounting Principles

(2) Tenneco presents the above reconciliation of GAAP to non-GAAP earnings measures primarily to reflect the results for the second quarters of 2007 and 2006 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 measures 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.

  Tenneco 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, substrate sales which
  the company previously referred to as pass-through sales include precious
  metals pricing, which may be volatile. Substrate sales occur when, at the
  direction of its OE customers, Tenneco purchases catalytic converters or
  components thereof from suppliers, uses them in its manufacturing
  processes and sells them as part of the completed system. While Tenneco
  original equipment customers assume the risk of this volatility, it
  impacts reported revenue. Excluding substrate sales removes this impact.
  Tenneco uses this information to analyze the trend in revenues before
  these factors. Tenneco believes investors find this information useful in
  understanding period to period comparisons in the company's revenues.

(1) Tenneco presents debt net of cash balances because management believes it is a useful measure of Tenneco's credit position and progress toward reducing leverage. The calculation is limited in that the company may not always be able to use cash to repay debt on a dollar-for- dollar basis.

(2) Tenneco presents the above reconciliation of the ratio debt net of cash to the last twelve months (LTM) of adjusted EBITDA to show trends that investors may find useful in understanding the company's ability to service its debt. For purposes of this calculation, adjusted LTM EBITDA is used as an indicator of the company's performance over the most recent twelve months and debt net of cash is presented as an indicator of our credit position and progress toward reducing our financial leverage. LTM adjusted EBITDA is used to reflect annual values and remove seasonal fluctuations. This reconciliation is provided as supplemental information and not intended to replace the company's existing covenant ratios or any other financial measures that investors may find useful in describing the company's financial position. See notes (1), (3) and (4) for a description of the limitations of using debt net of cash, EBITDA and adjusted EBITDA.

(3) EBITDA represents 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 Inc. has presented EBITDA because it regularly reviews EBITDA as a measure of the company's performance. In addition, Tenneco believes its debt holders utilize and analyze our EBITDA for similar purposes. Tenneco 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.

(4) Represents costs associated with changing new aftermarket customers from their prior suppliers to an inventory of our products. Although our aftermarket business regularly incurs changeover costs, we specifically identify in the table above those changeover costs that, based on the size or number of customers involved, we believe are of an unusual nature for the quarter in which they were incurred.

(5) In August 2006, we announced that we were freezing future accruals under our U.S. defined benefit pension plans for substantially all our U.S. salaried and non-union hourly employees effective December 31, 2006. In lieu of those benefits, we are offering additional benefits under defined contribution plan.

(6) The adjustment is related to our past administration of stock option grants and represents an adjustment for several prior years.

(7) Adjusted EBITDA is presented in order to reflect the results in a manner that allows a better understanding of operational activities separate from the financial impact of decisions made for the long term benefit of the company and other items impacting comparability between the periods. 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. 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.
