LCI INDUSTRIES Forward-Looking Statements This presentation contains certain “forward-looking statements” with respect to our financial condition, results of operations, business strategies, operating efficiencies or synergies, competitive position, growth opportunities, acquisitions, plans and objectives of management, markets for the Company’s common stock, the impact of legal proceedings, and other matters. Statements in this presentation that are not historical facts are “forward-looking statements” for the purpose of the safe harbor provided by Section 21E of the Securities Exchange Act of 1934, as amended, and Section 27A of the Securities Act of 1933, as amended, and involve a number of risks and uncertainties. Forward-looking statements, including, without limitation, those relating to the Company's future business prospects, net sales, expenses and income (loss), cash flow, financial condition, and addressable market, whenever they occur in this presentation are necessarily estimates reflecting the best judgment of the Company's senior management at the time such statements were made. There are a number of factors, many of which are beyond the Company’s control, which could cause actual results and events to differ materially from those described in the forward-looking statements. These factors include, in addition to other matters described in this presentation, pricing pressures due to domestic and foreign competition, costs and availability of, and tariffs on, raw materials (particularly steel and aluminum) and other components, seasonality and cyclicality in the industries to which we sell our products, availability of credit for financing the retail and wholesale purchase of products for which we sell our components, inventory levels of retail dealers and manufacturers, availability of transportation for products for which we sell our components, the financial condition of our customers, the financial condition of retail dealers of products for which we sell our components, retention and concentration of significant customers, the costs, pace of and successful integration of acquisitions and other growth initiatives, availability and costs of production facilities and labor, employee benefits, employee retention, realization and impact of expansion plans, efficiency improvements and cost reductions, the disruption of business resulting from natural disasters or other unforeseen events, the successful entry into new markets, the costs of compliance with environmental laws, laws of foreign jurisdictions in which we operate, other operational and financial risks related to conducting business internationally, increased governmental regulation and oversight, information technology performance and security, the ability to protect intellectual property, warranty and product liability claims or product recalls, interest rates, oil and gasoline prices and availability, the impact of international, national and regional economic conditions and consumer confidence on the retail sale of products for which we sell our components, and other risks and uncertainties discussed more fully under the caption “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, and in the Company’s subsequent filings with the Securities and Exchange Commission. Readers of this presentation are cautioned not to place undue reliance on these forward-looking statements, since there can be no assurance that these forward-looking statements will prove to be accurate. The Company disclaims any obligation or undertaking to update forward-looking statements to reflect circumstances or events that occur after the date the forward-looking statements are made, except as required by law. This presentation includes certain non-GAAP financial measures, such as adjusted Diluted Earnings Per Share and net debt to EBITDA leverage. These non-GAAP financial measures should not be considered a substitute for the comparable GAAP financial measures. Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measure are included in the Appendix to this presentation. This presentation also includes certain forward-looking non-GAAP financial measures, such as forward-looking targets for net debt to EBITDA leverage. The Company is unable to provide a reconciliation of forward-looking non-GAAP financial measures to their most directly comparable GAAP financial measures because the Company is unable to provide, without unreasonable effort, a meaningful or accurate calculation or estimation of amounts that would be necessary for the reconciliation due to the complexity and inherent difficulty in forecasting and quantifying future amounts or when they may occur. Such unavailable information could be significant to future results. 2

LCI INDUSTRIES Reconciliation of Non-GAAP Measures Adjusted Net Income and Adjusted Diluted Earnings per Share Income before Provision for Diluted earnings $ in millions, except per share amounts income taxes income taxes Net income Effective tax rate per share Year ended December 31, 2018 As reported GAAP $ 192.4 $ 43.8 $ 148.6 23 % $ 5.83 Impact of TCJA(1) — (0.6) 0.6 (1)% 0.03 Adjusted non-GAAP $ 192.4 $ 43.2 $ 149.2 22 % $ 5.86 Year ended December 31, 2017 As reported GAAP $ 212.84 $ 79.96 $ 132.88 38 % $ 5.24 Impact of TCJA(1) — (13.2) 13.2 (7)% 0.52 Adjusted non-GAAP $ 212.8 $ 66.8 $ 146.1 31 % $ 5.76 (1) The Company recorded one-time non-cash charges related to adjustments to deferred tax amounts from the December 2017 enactment of the Tax Cuts and Jobs Act (“TCJA”). In addition to reporting financial results in accordance with U.S. GAAP, the Company also provides non-GAAP measures that adjust for the impact of enactment of the TCJA. These items represent significant charges that impacted the Company’s financial results. Net income, diluted earnings per share, and the effective tax rate are all measures for which the Company provides the reported GAAP measure and an adjusted measure. The adjusted measures are not in accordance with, nor are they a substitute for, GAAP measures. The Company 30 considers these non-GAAP measures in evaluating and managing the Company’s operations. The Company believes that discussion of results adjusted for these items is meaningful to investors as it provides a useful analysis of underlying operating trends. The determination of these items may not be comparable to similarly titled measures used by other companies.

The Leverage Ratio (or Net Debt to EBITDA ratio) is a non-GAAP measure of the use of debt. The Leverage Ratio is calculated by dividing the total of long-term indebtedness, plus current portion of long-term debt, less cash and cash equivalents, by EBITDA. EBITDA, which is also a non-GAAP financial measure, is defined as the trailing twelve months earnings before interest, taxes, depreciation, and amortization. The Company uses the Leverage Ratio (or Net Debt to EBITDA ratio) as a metric to assess liquidity and the flexibility of its balance sheet. Consistent with other liquidity metrics, the Company monitors the Leverage Ratio as 31 a measure to determine the appropriate level of debt the Company believes is optimal to operate its business, and accordingly, to quantify debt capacity available for strategic capital allocation and deployment through investments in the business (capital expenditures, acquisitions, and strategic investments) and for returning capital to the shareholders (dividends and share repurchases). The priorities for capital allocation and deployment will change as circumstances dictate for the business, and the Leverage Ratio can be significantly impacted by the amount and timing of large expenditures requiring debt financing, as well as changes in profitability. The Leverage Ratio is a non-GAAP measure and should not be considered an alternative to cash flows provided by operating activities as a measure of liquidity. The Company's calculation of the Leverage Ratio may differ from similar calculations used by other companies, and therefore, comparability may be limited. The GAAP measure of Total Debt to Net Income ratio is calculated by dividing total debt by net income.
