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.

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, the impacts of costs and availability of, and tariffs on, raw materials (particularly steel and aluminum) and other components, future pandemics, geopolitical tensions, armed conflicts, or natural disasters on the global economy and on the Company's customers, suppliers, team members, business and cash flows, pricing pressures due to domestic and foreign competition, 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 and successful integration of acquisitions and other growth initiatives, availability and costs of production facilities and labor, team member benefits, team member 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, and 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, 2025, and in the Company’s subsequent filings with the Securities and Exchange Commission, including the Company's Quarterly Reports on Form 10-Q. 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 net income, adjusted net income per diluted share, adjusted EBITDA, adjusted EBITDA as a percentage of net sales, net debt to adjusted EBITDA leverage, and free cash flow. 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 presentation. This presentation also includes certain forward-looking non-GAAP financial measures, such as forward-looking guidance for adjusted diluted EPS. 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. Forward-Looking Statements 2LCI Industries | Q1 2026 Earnings Presentation

Adjusted EBITDA is defined as net income before interest expense, provision for income taxes, depreciation and amortization expense, and to the extent applicable, loss on extinguishment of debt, gain on sale of real estate, restructuring costs, and executive separation costs. Free cash flow is defined as net cash flows (used in) provided by operating activities less capital expenditures. The Company considers these non-GAAP measures in evaluating and managing the Company's operations and believes that discussion of results adjusted for these items is meaningful to investors because they provide a useful analysis of ongoing underlying trends. The adjusted measures are not in accordance with, nor are they a substitute for, GAAP measures, and they may not be comparable to similarly titled measures used by other companies. The net debt to Adjusted EBITDA ratio on a trailing twelve month basis is a non-GAAP performance measure included because the Company believes it is useful to investors in evaluating the Company's leverage. The net debt to Adjusted EBITDA ratio is defined as total debt, less cash and cash equivalents, divided by Adjusted EBITDA. The net debt to Adjusted EBITDA ratio is a non-GAAP measure and should not be considered a substitute for the ratio of total debt to net income determined in accordance with GAAP. The Company's calculation of its net debt to Adjusted EBITDA ratio might not be calculated in the same manner as, and thus might not be comparable to, similarly titled measures used by other companies.

20 Appendix Reconciliation of Non-GAAP Measures (cont.) ADJUSTED NET INCOME Three months ended March 31, ($ in thousands, except per share amounts) 2026 2025 Net income $ 62,947 $ 49,438 Loss on extinguishment of debt — 8,053 Tax effect of adjustment — (1,930) Adjusted net income $ 62,947 $ 55,561 Weighted average common shares outstanding - diluted 24,913 25,426 Dilutive effect of 2030 Convertible Notes (1) (580) — Weighted average common shares outstanding - adjusted diluted 24,333 25,426 ADJUSTED EPS Net income per common share - diluted $ 2.53 $ 1.94 Loss on extinguishment of debt — 0.32 Tax effect of adjustment — (0.07) Dilutive effect of 2030 Convertible Notes (1) 0.06 — Adjusted net income per common share - adjusted diluted (Adjusted EPS) $ 2.59 $ 2.19 (1) Weighted average shares outstanding - diluted, on a GAAP basis, includes diluted shares attributable to the Company's 2030 Convertible Notes. However, the offsetting impact of the convertible note hedge transactions that the Company entered into in connection therewith is not recognized on a GAAP basis. As a result, for purposes of this calculation, the Company excludes the dilutive shares to the extent they would be offset by the convertible note hedge transactions. In addition to reporting financial results in accordance with U.S. GAAP, the Company has provided the non-GAAP performance measures of adjusted net income and adjusted net income per adjusted diluted share ("Adjusted EPS") to illustrate and improve comparability of its results from period to period. Adjusted net income is defined as net income adjusted for loss on extinguishment of debt and the related tax effect during the three month periods ended March 31, 2026 and 2025. Adjusted EPS is defined as adjusted net income divided by weighted average common shares outstanding - adjusted diluted, which includes an adjustment for the dilutive effect of the 2030 Convertible Notes under the if-converted method for the three month period ended March 31, 2026. The Company considers these non-GAAP measures in evaluating and managing the Company's operations and believes that discussion of results adjusted for these items is meaningful to investors because it provides a useful analysis of ongoing underlying operating trends. These measures are not in accordance with, nor are they substitutes for, GAAP measures, and they may not be comparable to similarly titled measures used by other companies.
