Tenneco Reports Third Quarter Financial Results

• Record third quarter revenue of $1.8 billion
• Record third quarter EBIT of $111 million
• Cash from operations up 48% year-over-year to $118 million

LAKE FOREST, Ill.--(BUSINESS WIRE)--October 25, 2012--Tenneco Inc. (NYSE: TEN) reported third quarter net income of $125 million, or $2.05 per diluted share, which includes a benefit of $74 million, or $1.22 per diluted share, primarily related to the reversal of a U.S. tax valuation allowance. On an adjusted basis, net income rose to $52 million, or 85-cents per diluted share, compared with $42 million, or 67-cents per diluted share, a year ago.

Third quarter 2012 adjustments:

• Restructuring and related expenses of $7 million pre-tax, or 7-cents per diluted share;
• EBIT benefit of $5 million, or 5-cents per diluted share, from property recoveries related to transactions originated by The Pullman Company before being acquired by Tenneco in 1996;
• Net tax benefit of $74 million, or $1.22 per diluted share, primarily related to the reversal of the tax valuation allowance on the company’s U.S. net operating loss position and recording a tax valuation allowance in Spain for tax credits that may not be utilized due to tax losses there.

Third quarter 2011 adjustments:

• Restructuring and related expenses of $4 million pre-tax, or 5-cents per diluted share;
• Non-cash goodwill impairment charge of $11 million pre-tax, or 11-cents per diluted share, related to the Australian operations;
• Net tax charges of $2 million or 2-cents per diluted share, primarily related to tax adjustments based on filed tax returns.

Revenue

Total revenue in the quarter was $1.778 billion, compared with $1.773 billion in third quarter 2011. Revenue excluding substrate sales and currency increased 6% to $1.462 billion, versus $1.373 billion a year ago. The revenue increase was driven primarily by strong OE light vehicle production volumes in North America and China and incremental commercial vehicle revenue. In the third quarter, total OE commercial and specialty vehicle revenue increased 8% year-over-year to $184 million, and represented approximately 10% of total revenue.

EBIT and EBIT Margin

EBIT (earnings before interest, taxes and noncontrolling interests) increased 32% to $111 million compared with $84 million in third quarter 2011. Adjusted EBIT was $113 million versus $99 million, a 14% increase. EBIT includes a negative currency impact of $2 million. The improved EBIT results were driven by stronger light vehicle volumes in North America and China, incremental commercial vehicle revenue and effective operational cost control.

The company reported the following EBIT as a percent of revenue and EBIT as a percent of value-add revenue (revenue excluding substrate sales).

Cash

Cash generated from operations was $118 million in the quarter, a 48% year-over-year improvement from $80 million. The strong performance was driven by higher earnings and effective working capital management, particularly in inventories.

Tenneco continues to strategically invest in growth with capital expenditures in the quarter of $65 million, up from $50 million the prior year. The majority of spending was to support OE light and commercial vehicle program launches and new customer growth.

Debt

Tenneco’s net debt at September 30, 2012 was $1.138 billion, versus $1.141 billion the prior year. The leverage ratio (net debt to adjusted LTM EBITDA including noncontrolling interests) improved to 1.8x, versus 1.9x a year ago.

“Our North America and China operations drove revenue growth this quarter as we successfully capitalized on stronger light vehicle production volumes and benefited from higher global commercial vehicle revenue versus a year ago,” said Gregg Sherrill, chairman and CEO, Tenneco. “We delivered higher earnings and very good margins despite facing economic headwinds in Europe and South America. We also had a strong cash quarter on the strength of our earnings and working capital improvements."

THIRD QUARTER REPORTING SEGMENTS

North America EBIT increased to $77 million from $46 million one year ago. On an adjusted basis, EBIT was $72 million versus $46 million, a 57% increase. EBIT includes a favorable currency impact of $8 million year-over-year. EBIT performance was driven primarily by significant operational improvement in the North America OE ride control business, leveraging higher light vehicle volumes in both OE businesses and incremental commercial vehicle revenue.

Declining Europe aftermarket sales, lower volumes in the Europe OE ride control business and South America and a negative currency impact of $9 million, primarily in Brazil, contributed to a decrease in EBIT for Europe, South America and India. EBIT for the segment was $13 million compared with $36 million a year ago. On an adjusted basis, EBIT was $20 million versus $37 million.

Asia Pacific EBIT rose to $21 million compared with $2 million last year. The year-over-year comparison reflects a goodwill impairment charge of $11 million and restructuring charge of $3 million taken in third quarter 2011. On an adjusted basis, EBIT was $21 million versus $16 million, a 31% improvement. The EBIT increase was driven by strong volumes in China on current and new platforms, and the benefit from restructuring and operating improvements in Australia. Currency had a $1 million negative impact on Asia Pacific segment EBIT.

OUTLOOK

According to IHS Automotive forecasts, fourth quarter industry light vehicle production in the markets where Tenneco operates will be essentially flat year-over-year. Industry production in North America and China is forecasted to strengthen in the fourth quarter versus last year while Europe is expected to decline.

In North America, the company expects to leverage stronger industry light vehicle production volumes to drive year-over-year revenue growth. North America aftermarket revenue is expected to be in line with a strong fourth quarter a year ago.

Tenneco’s operations in China will drive results for the Asia Pacific region as the company expects fourth quarter revenue to increase versus last year. Tenneco’s strong position with market-leading OE customers in China and a forecasted rise in industry light vehicle production will drive the increase.

In the Europe, South America and India segment, Tenneco expects sustained economic weakness in Europe to negatively impact the segment results. According to IHS Automotive, Europe industry light vehicle production is forecasted to decline 10% in the fourth quarter. While Tenneco enjoys a strong customer and platform position, the company anticipates lower year-over-year revenue in both OE businesses due to the industry decline. Economic weakness throughout the region will also continue to impact the Europe aftermarket. In light of this weak industry environment, the company announced in the third quarter its intention to close an aftermarket manufacturing facility in Vittaryd, Sweden, which would eliminate 122 positions. This is a first step in Tenneco’s plans to further reduce fixed costs and better align its operations with the market in response to the ongoing economic challenges in Europe.

As the company has previously indicated, commercial vehicle markets around the world continue to be softer than anticipated and this weakness is expected to continue. For the fourth quarter, Tenneco estimates that revenue from its commercial and specialty vehicle business will be about even with the third quarter, which would result in approximately a 25% year-over-year increase in commercial vehicle revenue for the full year.

Tenneco is launching a strong book of business with leading commercial vehicle customers worldwide, which positions the company to capitalize on stronger volumes when industry production recovers. In the third quarter, the company further strengthened its position with the opening of its first manufacturing facility in Japan to supply diesel aftertreatment systems to Kubota, a leading global manufacturer of commercial vehicle engines and equipment. Tenneco also announced that it will supply Scania with Euro VI on-road diesel aftertreatment systems in Europe and diesel aftertreatment in South America.
