Use of Projections and Financial Information and Forward-Looking Statements Certain statements in this communication, including the estimated guidance provided under “Financial Performance” 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 International Group, Inc.’s (“Janus”) positioning in the industry to strengthen its pipeline and deliver on its objectives and Janus’ belief regarding the demand outlook for Janus’ products and the strength of the industrials markets. When used in this communication, words such as “may,” “should,” “could,” “would,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “continue,” or the negative of such terms or other similar expressions, as they relate to the management team, identify forward-looking statements. Such forward-looking statements are based on the current beliefs of Janus’ management, based on currently available information, as to the outcome and timing of future events, and involve factors, risks, and uncertainties that may cause actual results in future periods to differ materially from such statements. In addition to factors previously disclosed in Janus’ reports filed with the Securities and Exchange Commission (“SEC”) and those identified elsewhere in this communication, the following factors, among others, could cause actual results to differ materially from forward-looking statements or historical performance: (i) risks of the self-storage industry; (ii) the highly competitive nature of the self-storage industry and Janus’ ability to compete therein; and (iii) the risk that the demand outlook for Janus’ 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 as well as any risks or uncertainties discussed in our filings with the SEC, including without limitation, under the heading “Risk Factors” in Janus’ registration statement on Form S-4 initially filed with the SEC on February 8, 2021, as amended, registration statement on Form S-1, initially filed with the SEC on July 7, 2021, as amended, most recently filed Quarterly Report on Form 10-Q and its subsequent filings with the SEC. The recipient of this presentation acknowledges that it is (a) aware that United States securities laws prohibit any person who has material, non-public information concerning a company from purchasing and selling securities of such company or from communicating such information to any other person under circumstances in which it is reasonably foreseeable that such person may purchase or sell such securities and (b) that the recipient will neither use, nor cause any third party to use this investor presentation or any information contained herein in violation of the Securities Exchange Act of 1934, as amended, including, without limitation, Rule 10b-5 thereunder. Financial Information Janus uses measures of performance that are not required by or presented in accordance with generally accepted accounting principles in the United States of America (“GAAP”). 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. Management Adjusted EBITDA is a non-GAAP financial measure 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 Management Adjusted EBITDA provides useful information to investors and others in understanding and evaluating Janus’ operating results in the same manner as its management and board of directors and in comparison with Janus’ peer group companies. In addition, Management Adjusted EBITDA provides useful measures for period-to-period comparisons of Janus’ 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. Management Adjusted EBITDA is defined as net income excluding interest expense, income taxes, depreciation expense, amortization, sponsor management fees, acquisition expenses, Nokē-related startup costs, and other non-operational, non-recurring items. Management Adjusted EBITDA 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 Management Adjusted EBITDA rather than net income (loss), which is the nearest GAAP equivalent of Management Adjusted EBITDA. 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. Disclaimer 2
