ICE expected to continue as dominant powertrain well into future

Tenneco products offer emissions solutions to 98% of powertrain applications in 2027 and beyond

– GDI + GDI Hybrid is leading powertrain by 2027, requiring 3-way catalyst, gasoline particulate filter (GDF) and advanced thermal management

– US Tier 3 fully in effect, requiring an average 81% reduction in NOx + NMOG compared to 2015 fleet average

– EU Real Driving Emissions and US Tier 3 will require compact mixing and high efficiency SCR for diesel applications

** In April 2015, the FASB issued Accounting Standard Update 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated liability. Tenneco adopted this standard for the first quarter of 2015 and applied retrospectively to 2014. The balance for unamortized debt issuance costs was $12 million and $14 million at December 31, 2015 and December 31, 2014, respectively.

Tenneco’s revenue projections for 2016 are as of April 2016 and projections for 2017 and 2018 are as of January 2016. Revenue assumptions are based on projected customer production schedules, IHS Automotive December 2015 forecasts and Power Systems Research January 2016 forecasts.

In addition to the information set forth on this slide and slide 21, Tenneco’s revenue projections are based on the type of information set forth under “Outlook” in Item 7 – “Management’s Discussion and Analysis of Financial Condition and Results of Operations” as set forth in Tenneco’s Annual Report on Form 10-K for the year ended December 31, 2015. Pleasesee that disclosure for further information. Key additional assumptions and limitations described in that disclosure include:

• Revenue projections are based on original equipment manufacturers’ programs that have been formally awarded to the company; programs where the company is highly confident that it will be awarded business based on informal customer indications consistent with past practices; and Tenneco’s status as supplier for the existing program and its relationship with the customer.

• Revenue projections are based on the anticipated pricing of each program over its life.

• Revenue projections assume a fixed foreign currency value. This value is used to translate foreign business to theU.S. dollar.

• Revenue projections are subject to increase or decrease due to changes in customer requirements, customer and consumer preferences, the number of vehicles actually produced by our customers and pricing.

• Use of Non-GAAP Financial InformationIn addition to the results reported in accordance with accounting principles generally accepted in the United States (“GAAP”) included in this presentation, the company has provided information regarding certain non-GAAP financial measures. These measures include Earnings Before Interest Expense, Income Taxes, Noncontrolling Interests and Depreciation and Amortization (“EBITDA*”), Net Debt, Working Capital, Value-Add Revenue, Adjusted EBITDA*, and Adjusted Earnings Before Interest Expense, Income Taxes and Noncontrolling Interests (“Adjusted EBIT”).

EBITDA* represents earnings before interest expense, income taxes, noncontrolling interests 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. 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 that its security holders utilize and analyze its 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 non-GAAP results in order to reflect the results for full years 2000 through 2015 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.* Including noncontrolling interests.

Note: We present debt net of cash balances because management believes it is a useful measure of our credit position and progress toward reducing leverage. The calculation is limited in that we may not always be able to use cash to repay debt on a dollar-for-dollar basis.


** In April 2015, the FASB issued Accounting Standard Update 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated liability. Tenneco adopted this standard for the first quarter of 2015 and applied retrospectively to 2014. The balance for unamortized debt issuance costs was $12 million and $14 million at December 31, 2015 and December 31, 2014, respectively.

We include total receivables, inventory and payables in the calculation as these are the components of working capital that we have the most direct control over and because they are most closely related to the cash flow performance of our operations.

Adjusted EBIT as a Percentage of Value-Add Revenue – Reconciliation of Non-GAAP Results

(1) Tenneco presents the above reconciliation of revenues in order to reflect value-add revenues separately from substrate sales, which include precious metals pricing, which may be volatile. Substrate sales occur when, at thedirection 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 originalequipment 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 this factor. Tenneco believes investors find this information useful in understanding period to period comparisons in the company’s revenues.
