Tenneco Reports Second Quarter Results

• Highest-ever quarterly revenue of $2.1 billion
• Highest-ever quarterly EBIT of $141 million
• Record second quarter cash from operations of $133 million

LAKE FOREST, Ill.--(BUSINESS WIRE)--July 29, 2013--Tenneco Inc. (NYSE:TEN) reported second quarter net income of $63 million, or $1.02 per diluted share, compared with net income of $87 million, or $1.42 per diluted share in second quarter 2012. On an adjusted basis, net income was $68 million, or $1.10 per diluted share, versus $70 million, or $1.14 per diluted share a year ago. The decrease in net income and earnings per share was more than explained by a higher year-over-year tax rate.

Revenue

Total revenue was $2.067 billion, up 8% from prior year, driven by revenue increases in both the Clean Air and Ride Performance businesses. Clean Air revenue increased 10% to $1.406 billion, on stronger light vehicle production in North America, China and South America as well as revenue growth in both the light and commercial vehicle businesses in Europe. Ride Performance revenue rose 2% versus prior year to $661 million, largely driven by strong light vehicle production in China.

Value-add revenue (revenue excluding substrate sales) was $1.579 billion, up 6% year-over-year.

“We delivered another solid quarter with top-line growth in both product divisions driven by stronger global light vehicle production, higher commercial vehicle revenue in Europe and South America and a solid contribution from our global aftermarket business,” said Gregg Sherrill, chairman and CEO, Tenneco. “I am also pleased that we delivered record-high EBIT and adjusted EBIT. In addition, our outstanding effort in managing working capital drove our best-ever second quarter performance for generating cash from operations.”

Global OE light vehicle revenue increased 10% year-over-year to $1.483 billion with light vehicle growth in nearly all regions due to the ramp-up on new programs and leveraging higher industry production with a strong platform mix. OE commercial and specialty vehicle revenue increased 5% to $237 million in the quarter, compared with $226 million a year ago. The increase was due to commercial vehicle revenue gains in Europe and South America. Global aftermarket revenue increased 1% to $347 million.

EBIT

EBIT (earnings before interest, taxes and noncontrolling interests) was $141 million, up from $137 million in second quarter 2012. Adjusted EBIT was $148 million, up from $139 million a year ago. The year-over-year comparison includes unfavorable currency impacts of $8 million.

The adjusted EBIT improvement reflects a 15% increase in Clean Air adjusted EBIT, driven by light vehicle volumes in North America, China and South America and effective operational cost management. Ride Performance adjusted EBIT also improved year-over-year, up 4% on stronger volumes in China.

In addition to the items set forth above, the tables at the end of this press release reconcile GAAP to non-GAAP results.

Second Quarter 2013 adjustments:

• Restructuring and related expenses of $7 million pre-tax, or 8-cents per diluted share.

Second Quarter 2012 adjustments:

• Restructuring and related expenses of $2 million pre-tax, or 2-cents per diluted share;
• Costs related to refinancing of $1 million pre-tax or 1-cent per diluted share;
• Net tax benefits of $19 million, or 31-cents per diluted share, primarily related to U.S. taxable income with no associated tax expense due to the valuation allowance on the company’s net operating loss position.

EBIT Margin

The company’s operational performance and ability to capitalize on higher light vehicle production in key regions drove an increase in adjusted EBIT margin on value-add revenue.

Tenneco reported the following EBIT as a percent of revenue and EBIT as a percent of value-add revenue.

Cash

Cash generated by operations in the quarter was $133 million, up 55% from $86 million in second quarter 2012. The record second quarter cash performance was primarily driven by working capital improvements including strong year-over-year improvement in inventories.

Capital expenditures in the second quarter were $47 million, compared with $62 million a year ago. The majority of the capital spending was to support Clean Air customer programs in North America, Europe and China.

Taxes

The tax rate in the quarter was 39%, up from 18% in the second quarter of last year. The higher rate was primarily due to the reversal of the U.S. tax net operating loss valuation allowance in the third quarter of 2012, and to an increase in unbenefitted foreign losses in certain countries.

For the remainder of the year, the company anticipates a tax rate between 36% and 38%, and 2013 cash taxes to be approximately $110 million.

Outlook

In the third quarter, IHS Automotive forecasts a 4% increase in global light vehicle production versus a year ago with both North America and China increasing 8% year-over-year. South America is expected to be even with last year and production declines of 3% are expected in Europe.

Tenneco is well-positioned to capitalize on the stronger global light vehicle production environment with an excellent platform mix, the continued ramp-up on new programs and a well-established footprint in the fastest growing markets.

In general, the global commercial vehicle market remains relatively weak. There is modest demand improvement in certain areas; however, inventory corrections are still expected to impact production levels. The company anticipates its commercial vehicle revenues for the next two quarters will be relatively flat compared with the second quarter, bringing full year revenues within the lower end of the company's previously announced range.

“While industry conditions globally are somewhat mixed, I am pleased with our performance through the first half of the year,” said Sherrill. “For the remainder of the year, our Clean Air and Ride Performance businesses are staying focused on improving operating performance and driving profitable growth. With this focus we anticipate continued improvement by capitalizing on stronger light vehicle production and our global position in the commercial vehicle market.”

⁽¹⁾ Generally Accepted Accounting Principles

⁽²⁾ EBITDA including noncontrolling interests represents income before interest expense, income taxes, noncontrolling interests and depreciation and amortization. EBITDA including noncontrolling interests is not a calculation based upon generally accepted accounting principles. The amounts included in the EBITDA including noncontrolling interests calculation, however, are derived from amounts included in the historical statements of income data. In addition, EBITDA including noncontrolling interests should not be considered as an alternative to net income (loss) attributable to Tenneco Inc. 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 including noncontrolling interests because it regularly reviews EBITDA including noncontrolling interests as a measure of the company's performance. In addition, Tenneco believes its investors utilize and analyze our EBITDA including noncontrolling interests for similar purposes. Tenneco also believes EBITDA including noncontrolling interests 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 including noncontrolling interests 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 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 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. 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.

⁽²⁾ Tenneco presents the above reconciliation of revenues in order to reflect value-add revenues separately from the effects of doing business in currencies other than the U.S. dollar. Additionally, substrate 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.
