Use of Non-GAAP Financial Information

In 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, Value-Add Revenue, Adjusted EBITDA*, Adjusted Earnings Before Interest Expense, Income Taxes and Noncontrolling Interests (“Adjusted EBIT”), Adjusted Earnings Per Share, and Return on Invested Capital. Reconciliations of these non-GAAP financial measures to the comparable GAAP measure are included in this presentation.

Tenneco Projections

36

Tenneco’s revenue outlook for 2018 is as of January 2018. Revenue assumptions are based on projected customer production schedules, IHS Automotive January 2018 forecasts, Power Systems Research January 2018 forecasts and Tenneco estimates.

Tenneco’s revenue outlook for 2020 is as of January 2018. Revenue assumptions are based on projected customer production schedules, IHS Automotive January 2018 forecasts, Power Systems Research January 2018 forecasts and Tenneco estimates.

In addition to the information set forth on slide 4, 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, 2017. Please see 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.

• Except as otherwise indicated, revenue projections assume a fixed foreign currency value. This value is used to translate foreign business to the U.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.

Certain elements of the restructuring and related expenses, legal settlements and other unusual charges we incur from time to time cannot be forecasted accurately. In this respect, we are not able to forecast EBIT (and the related margins) on a forward-looking basis without unreasonable efforts on account of these factors and the difficulty in predicting GAAP revenues (for purposes of a margin calculation) due to variability in production rates and volatility of precious metal pricing in the substrates that we pass through to our customers.

Tenneco’s revenue projection constitutes a forward-looking statement. We also refer you to the cautionary language regarding our forward-looking statements set forth in the Safe Harbor statement on slide 2.

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

37

(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 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 this factor. Tenneco believes investors find this information useful in understanding period to period comparisons in thecompany's revenues.

(2) Generally Accepted Accounting Principles.(3) 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.

(4) Tenneco presents adjusted EBIT as a percentage of value-add revenue to assist investors in evaluating our company’s operational performance without the impact of substrate sales.

(1) Generally accepted Accounting Principles(2) Tenneco presents the above reconciliation of non-GAAP results in order to allow a better understanding of our performance.(3) We consider Return on Invested Capital (ROIC) to be a meaningful indicator of our operating performance, and we evaluate ROIC because it measures how effectively we use the capital we invest in our operations. Tenneco defines ROIC as tax effected

Adjusted EBIT divided by Average Invested Capital, which is the beginning and ending balances of debt, equity and noncontrolling interests. See the tabular calculation above.
