Tenneco Reports Third Quarter Results

• Revenue of $1.773 billion, up 15%
• Highest-ever third quarter net income of $30 million
• $63 million year-over-year improvement in cash from operations

LAKE FOREST, Ill.--(BUSINESS WIRE)--October 28, 2011--Tenneco Inc. (NYSE: TEN) reported a significant increase in net income to $30 million, or 49-cents per diluted share, versus $10 million, or 17-cents per diluted share, in third quarter 2010. On an adjusted basis, net income also increased to $42 million, or 67-cents per diluted share, versus $24 million, or 39-cents per diluted share, a year ago. The tables in this press release reconcile GAAP results to non-GAAP results.

“Our revenue this quarter reflects Tenneco’s excellent growth opportunities with our position on strong-selling vehicles worldwide and expansion into the commercial vehicle segment, where our launch execution is on track and delivering results,” said Gregg Sherrill, chairman and CEO, Tenneco. “Our earnings continue to improve, driven by strong performances globally, despite headwinds of higher year-over-year operational costs in the North America OE ride control business.”

REVENUE

Total revenue in the quarter was $1.773 billion, up 15% from $1.542 billion a year ago. Value-add revenue (revenue minus substrate pass thru sales) was $1.373 billion, up 16% year-over-year versus $1.185 billion. Stronger OE volumes on current and new platforms drove the increase, coupled with a 9% rise in global aftermarket sales. The launch and ramp-up of new commercial vehicle platforms grew commercial and specialty vehicle OE revenue to 12% of total OE revenue. Revenue included $51 million in favorable currency.

EBIT AND EBIT MARGIN

EBIT (earnings before interest, taxes and noncontrolling interests) was $84 million, a record-high for the third quarter and up from $67 million a year ago. Adjusted EBIT improved to $99 million, compared with $77 million in third quarter 2010. The EBIT improvement was driven by higher OE light vehicle volumes, new commercial vehicle business and higher global aftermarket sales; together contributing a $25 million increase. Partially offsetting these factors was $10 million in higher year-over-year operational costs in the North America OE ride control business, which faced headwinds in material costs and manufacturing inefficiencies. Currency had a $7 million favorable impact on EBIT.

The company also took an $11 million goodwill impairment charge for its Australian operations and benefited from a $10 million expense reduction this quarter for deferred and long-term compensation indexed to the company’s stock price.

“We remain focused on continuing to improve our operating margins globally including in North America where we are addressing operational issues in our ride control business as we transition and consolidate production at one of our plants,” said Sherrill.

EBIT as a percent of revenue and EBIT as a percent of value-add revenue improved year-over-year as noted in the chart below.

In addition to the factors above, EBIT margin was negatively impacted by a mix shift due to a lower percentage of total revenue generated by the higher-margin aftermarket business.

ADJUSTED THIRD QUARTER 2011 AND 2010 RESULTS

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.

Third quarter 2010 adjustments:

• Restructuring and related expenses of $6 million pre-tax, or 6-cents per diluted share;
• A charge of $4 million pre-tax, or 4-cents per diluted share, related to an actuarial loss for a lump-sum pension payment;
• Costs of $5 million pre-tax, or 6-cents per diluted share, related to refinancing the company’s 10.25 percent notes with new 7.75 percent notes;
• Non-cash tax charges of $4 million, or 6-cents per diluted share, primarily related to the impact of recording a valuation allowance against our tax benefit for losses in certain foreign jurisdictions.

CASH

Cash from operations was $80 million, up significantly from $17 million a year ago. The improvement was due to a $51 million improvement in cash used for working capital, primarily accounts receivables and inventories.

Tenneco continues to invest in growth. Capital expenditures in the quarter were $50 million versus $34 million a year ago. These investments were primarily to support emission control technology applications for new customer programs and continued capacity investments for expanding business in China. The company still expects its capital expenditures to be in the range of $190 million to $210 million for full-year 2011. Separately, Tenneco paid $4 million to acquire the remaining 25% interest in the company’s emission control joint venture in Thailand, now wholly-owned by Tenneco.

In the third quarter, Tenneco repurchased 129,500 shares of its outstanding common stock for $5 million, completing a previously announced 400,000 share stock buyback plan to offset dilution from shares issued to employees in 2011.

DEBT

Net debt at September 30, 2011 was $1.141 billion, versus $1.113 billion a year ago.

The leverage ratio (net debt to adjusted LTM EBITDA including noncontrolling interests) improved to 1.9x, compared with 2.2x at the end of third quarter 2010.

OUTLOOK

Overall, IHS Automotive forecasts that production will increase 2% in the regions where Tenneco operates. Light vehicle production is expected to be up 12% in North America, 2% in China, 1% in South America and 8% in Australia. Europe is forecasted to be down 2% and India down 8%.

Tenneco continues to launch and ramp-up production on new commercial vehicle programs in North America, Europe, China and South America. The company remains confident in its total OE revenue guidance for 2011. It now expects that commercial vehicle OE revenue will be approximately $650 million for the full year, entirely due to lower volumes related to launch timing and ramp-up schedules, primarily in the Europe segment.

“In the fourth quarter, we expect our revenue growth to continue outpacing global industry light vehicle production due to our strong platform position worldwide and incremental commercial vehicle revenue,” said Sherrill. “We are executing well on our growth plans fueled by our advanced technology, application engineering capabilities and expanding presence in the fastest-growing markets. In the third quarter, we expanded our commercial vehicle customer base by winning new emission control business with a commercial vehicle customer in Japan.”

THIRD QUARTER REPORTING SEGMENTS

NORTH AMERICA

• Tenneco’s content on strong selling vehicles including the Ford F-150 pick-up, Ford Focus and the VW Jetta drove a 13% OE revenue increase, excluding currency and substrate sales, versus a 6% increase in industry light vehicle production. Incremental revenue from commercial vehicle programs also contributed to the increase.
• Aftermarket revenue increased on continued strong demand in both product lines.
• EBIT was $46 million, compared with $42 million a year ago, which included restructuring and a pension charge. Adjusted EBIT was $46 million, versus $51 million. Both include $5 million in negative currency. Higher OE volumes and aftermarket sales, the impact of new commercial vehicle programs and lower deferred and long-term compensation expense were offset by higher operational costs in the North America OE ride control business.

EUROPE, SOUTH AMERICA AND INDIA

• Europe OE revenue was up 16%, excluding currency and substrate sales, versus an industry light vehicle production increase of 2%. Strong volumes on key platforms including the Mercedes CLS, VW Polo, Daimler CLS and Audi A4 drove the gain.
• Higher aftermarket ride control revenue was more than offset by lower emission control revenue due to market declines.
• South America and India revenue, excluding currency and substrate sales, was up 12% versus industry light vehicle production increases of 4% in South America and 3% in India.
• Europe, South America and India EBIT increased to $36 million, from $15 million a year ago. Adjusted for $1 million in restructuring costs this year, EBIT rose to $37 million versus $15 million. The increase was driven by higher OE volumes in all regions and lower deferred and long-term compensation expense, partially offset by a Europe aftermarket mix shift toward Eastern Europe. 2011 EBIT includes $10 million in positive currency.

ASIA PACIFIC

• Asia revenue, up 24% excluding currency and substrate sales, was driven by volume strength in China on key platforms with Nissan, Audi and Volkswagen.
• Australia revenue excluding currency and substrate sales declined on lower OE volumes.
• Asia Pacific EBIT was $2 million, compared with $10 million a year ago. Adjusted EBIT was $16 million, up from $11 million in third quarter 2010, driven by higher China volumes and lower deferred and long-term compensation expense, partially offset by volume declines in Australia. This year’s quarter includes the goodwill impairment charge of $11 million and $3 million in restructuring costs, related to permanently eliminating 53 positions in Australia. The company expects its Australia performance to stabilize with the positive impact of these actions. Third quarter 2010 includes a restructuring charge of $1 million. Currency has a $2 million positive impact on 2011 EBIT.
