2JanusIntl.com Forward-Looking Statements Certain statements in this communication, including the estimated guidance provided under “2026 Guidance and Key Planning Assumptions,” “Long-Term Fundamentals and Investment Highlights” and “Positioned for Sequential Margin Improvement”, herein, may be considered “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements other than statements of historical fact included in this communication are forward-looking statements, including, but not limited to statements regarding Janus’s belief regarding the demand outlook for Janus’s products and the strength of the industrials markets. When used in this communication, words such as “plan,” “believe,” “expect,” “anticipate,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “continue,” “could,” “may,” “might,” “possible,” “potential,” “predict,” “should,” “would,” “will,” and other similar words and expressions or the negative of such terms or other similar expressions, identify forward-looking statements. The forward-looking statements contained in this communication are based on our current expectations and belief concerning future developments and their potential effects on us. We cannot assure you that future developments affecting us will be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. Some factors that could cause actual results to differ include, but are not limited to: (i) risks of the self-storage industry; (ii) the highly competitive nature of the self-storage industry and Janus’s ability to compete therein; (iii) litigation, complaints, and/or adverse publicity; (iv) general economic conditions, including the capital and credit markets, and adverse macroeconomic conditions, including unemployment, inflation, supply chain constraints, tariffs and trade restrictions, geopolitical conflicts, fluctuating interest rates, changes in consumer practices due to slower economic growth, and regional or global liquidity constraints; (v) cyber incidents or directed attacks that could result in information theft, data corruption, operational disruption and/or financial loss; (vi) risks related to our share repurchase program; (vii) the risk that we will not be able to successfully integrate and develop Kiwi II Construction into our operations; (viii) inability to realize expected benefits and efficiencies from our cost-savings initiatives and restructuring activities; and (ix) the risk that the demand outlook for Janus’s products may not be as strong as anticipated. There can be no assurance that the events, results, trends or guidance regarding financial outlook identified in these forward-looking statements will occur or be achieved. Forward-looking statements speak only as of the date they are made, and Janus is not under any obligation and expressly disclaims any obligation, to update, alter or otherwise revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law. This communication is not intended to be all-inclusive or to contain all the information that a person may desire in considering an investment in Janus and is not intended to form the basis of an investment decision in Janus. All subsequent written and oral forward-looking statements concerning Janus or other matters and attributable to Janus or any person acting on its behalf are expressly qualified in their entirety by the cautionary statements above and under the heading “Risk Factors” in Janus’s most recently filed Annual Report on Form 10-K and any subsequent Quarterly Report on Form 10-Q, as updated from time to time in amendments and its subsequent filings with the SEC.

3JanusIntl.com Non-GAAP Financial Measures Janus uses measures of performance that are not required by or presented in accordance with GAAP in the United States. Non-GAAP financial performance measures are used to supplement the financial information presented on a GAAP basis. These non-GAAP financial measures should not be considered in isolation or as a substitute for the relevant GAAP measures and should be read in conjunction with information presented on a GAAP basis. Please see the Appendix of this presentation, which includes definitions of non-GAAP measures and metrics used in this presentation and reconciliations of non-GAAP measures to the most directly comparable GAAP measure. Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Diluted EPS, Free Cash Flow, Free Cash Flow Conversion of Adjusted Net Income, and Net Leverage Ratio are non-GAAP financial measures used by Janus to evaluate its operating performance, generate future operating plans, and make strategic decisions, including those relating to operating expenses and the allocation of internal resources. Accordingly, Janus believes these non-GAAP financial measures provide useful information to investors and others in understanding and evaluating Janus’s operating results in the same manner as its management and board of directors and in comparison with Janus’s peer group companies. In addition, these non-GAAP financial measures provide useful measures for period-to-period comparisons of Janus’s business, as they remove the effect of certain non-recurring events and other non-recurring charges, such as acquisitions, and certain variable or non-recurring charges. Adjusted EBITDA is defined as net income excluding interest expense, income taxes, depreciation expense, amortization, and other non-operational, non-recurring items. Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by total revenue. Adjusted Net Income is defined as net income as adjusted for the corresponding tax-adjusted add-backs shown in the Adjusted EBITDA reconciliation. Adjusted Diluted EPS is defined as Adjusted Net Income divided by the diluted weighted average number of shares outstanding. Free Cash Flow is calculated by subtracting capital expenditures from cash provided by operating activities. Free Cash Flow Conversion of Adjusted Net Income is calculated as free cash flow divided by Adjusted Net Income. Net Leverage Ratio is defined as the ratio of our consolidated senior secured indebtedness reduced by cash to our trailing four-quarter consolidated Adjusted EBITDA. Please note that the Company has not provided the most directly comparable GAAP financial measure, or a quantitative reconciliation thereto, for the Adjusted EBITDA and Inorganic Revenue forward-looking guidance for 2026 included in this communication in reliance on the "unreasonable efforts" exception provided under Item 10(e)(1)(i)(B) of Regulation S-K. Providing the most directly comparable GAAP financial measure, or a quantitative reconciliation thereto, cannot be done without unreasonable effort due to the inherent uncertainty and difficulty in predicting certain non-cash, material and/or non-recurring expenses or benefits, legal settlements or other matters, and certain tax positions. Because these adjustments are inherently variable and uncertain and depend on various factors that are beyond the Company's control, the Company is also unable to predict their probable significance. The variability of these items could have an unpredictable, and potentially significant, impact on our future GAAP financial results, and amounts excluded from these non-GAAP measures in future periods could be significant. Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Diluted EPS, Free Cash Flow, Free Cash Flow Conversion of Adjusted Net Income, and Net Leverage Ratio should not be considered in isolation of, or as an alternative to, measures prepared in accordance with GAAP. There are a number of limitations related to the use of these non-GAAP measures rather than the nearest GAAP equivalent of Adjusted EBITDA and Adjusted Net Income. These limitations include that the non-GAAP financial measures: exclude depreciation and amortization, and although these are non-cash expenses, the assets being depreciated may be replaced in the future; do not reflect interest expense, or the cash requirements necessary to service interest on debt, which reduces cash available; do not reflect the provision for or benefit from income tax that may result in payments that reduce cash available; exclude non-recurring items (i.e., the extinguishment of debt); and may not be comparable to similar non-GAAP financial measures used by other companies, because the expenses and other items that Janus excludes in the calculation of these non-GAAP financial measures may differ from the expenses and other items, if any, that other companies may exclude from these non-GAAP financial measures when they report their operating results. Because of these limitations, these non-GAAP financial measures should be considered along with other operating and financial performance measures presented in accordance with GAAP.
