JANUS INTERNATIONAL GROUP REPORTS SECOND QUARTER 2022 FINANCIAL RESULTS

Delivered 42.2% revenue growth, including 27.4% organic improvement

Delivered over 41% increase in Adjusted EBITDA to $50.7 million; Net Income grew to $22.8 million

Sequential Adjusted EBITDA margin improvement of approximately 100 basis points from Q1 2022 and over 200 basis points from Q4 2021

Sequential Net Income growth of approximately 16% from Q1 2022 and over 122% from Q4 2021

Raises full-year 2022 revenue and Adjusted EBITDA outlook

TEMPLE, GA, August 16, 2022 – Janus International Group, Inc. (NYSE: JBI) (“Janus” or the “Company”), a leading provider of cutting-edge access control technologies and building product solutions for the self-storage and other commercial and industrial sectors, today announced financial results for the second quarter ended July 2, 2022.

Second Quarter 2022 Highlights

•Revenues of $247.7 million, a 42.2% increase compared to $174.2 million for the second quarter of 2021, driven primarily by strong performance across all sales channels, including Commercial and Other up 81.6%, Restore, Rebuild & Replace (“R3”) up 34.3%, and New Construction up 17.3%, along with a $25.8 million contribution from the 2021 acquisitions of DBCI and ACT.

•Adjusted EBITDA (defined as net income plus the corresponding add-backs shown in the Adjusted EBITDA reconciliation tables below) of $50.7 million, a 41.1% increase compared to $35.9 million for the second quarter of 2021, driven by increased revenue from all sales channels, partially offset by incremental general and administrative expenses. Adjusted EBITDA as a percentage of revenues was 20.5%, a decrease of approximately 10 basis points from the prior year period due primarily to higher costs impacting raw material, labor and logistics in advance of commercial actions and productivity initiatives taking full effect, as well as incremental costs associated with being a public company. However, as a result of volume growth, productivity initiatives and commercial actions, Adjusted EBITDA margins increased by approximately 100 basis points over the first quarter of 2022 and over 200 basis points over the fourth quarter of 2021.

•Net income was $22.8 million, or $0.16 per diluted share, compared to a $1.7 million loss, or $(0.02) per diluted share in the second quarter of 2021.

•Adjusted Net Income (defined as Net Income plus the corresponding tax-adjusted add-backs shown in the Adjusted Net Income reconciliation tables below) of $24.8 million, up 20.4% compared to $20.6 million in the second quarter of 2021. Adjusted Net Income per diluted share was $0.17, compared to $0.25 per diluted share in the prior year quarter. The decrease in Adjusted Net Income per diluted share versus the prior year quarter was due to the increase in the weighted average number of outstanding shares as a result of the business combination in June of 2021, partially offset by higher Adjusted Net Income.

•Operating cash flow of $18.4 million compared to $19.3 million in the second quarter of 2021. Free cash flow was $16.0 million compared to $17.6 million in the second quarter of 2021,

1

reflecting continued strong free cash flow conversion of 65% of Adjusted Net Income, despite the continued investments in working capital to support the ongoing growth of the business.

•Quarter end leverage ratio of 3.9x – a decrease of 0.4x from Q1 2022, with continued focus on de-levering the business towards goal of 2.5x - 3.5x.

Ramey Jackson, Chief Executive Officer, stated, “The strong momentum we established to start the year continued in the second quarter. We once again generated substantial year-over-year revenue growth from all of our sales channels, led again by particular strength in our Commercial and Other and R3 sales channels. We were particularly pleased to see a second consecutive quarter of strong sequential EBITDA margin improvement, highlighting how the commercial actions and the cost savings initiatives we have undertaken are yielding impressive results.”

Mr. Jackson continued, “Even as macroeconomic concerns around inflation, currency, labor availability, and supply chains persist, high occupancy rates in the self-storage industry continue to support pricing power for our customers that in turn is driving increasing levels of investment in both existing and new facilities. With our market-leading product offerings and solutions across self-storage, commercial, and industrial end markets, and supported by our strong cash generation profile, we are well situated to benefit from these tailwinds. Given the strong first half results, our expectations for the balance of the year, and a focus on driving continued margin improvement, we are pleased to raise our full-year 2022 outlook.”

2022 Financial Outlook:

Based on the Company’s current business outlook, Janus is raising its full-year 2022 outlook as follows:

•Revenue in a range of $940 million to $960 million, up from the previous range of $890 million to $910 million. The new range represents a 26.6% increase at the midpoint as compared to 2021 levels.

•Adjusted EBITDA in a range of $204 million to $211 million, up from the previous range of $193 million to $200 million. The new range represents a 40.0% increase at the midpoint as compared to 2021 levels.

Forward Looking Statements

Certain statements in this communication, including the estimated guidance provided under “2022 Financial Outlook” herein, may be considered “forward-looking statements” within the meaning of

2

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 positioning in the industry to strengthen its pipeline and deliver on its objectives and 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 “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’s 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’s reports filed with the 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’s ability to compete therein; and (iii) 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 Quarterly Report on Form 10-Q, as updated from time to time in amendments and its subsequent filings with the SEC.

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.

Adjusted EBITDA, Adjusted Net Income, Adjusted Basic EPS, and Adjusted Diluted EPS 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 Adjusted EBITDA, Adjusted Net Income, Adjusted Basic EPS, and Adjusted Diluted EPS 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, Adjusted EBITDA, Adjusted Net Income, Adjusted Basic EPS, and Adjusted Diluted EPS 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 Net Income is defined as net income plus the corresponding tax-adjusted add-backs shown in the Adjusted EBITDA reconciliation. Adjusted Basic earnings (income) per share (EPS) is computed by taking Adjusted Net Income divided by the weighted average number of shares of common stock outstanding during the period. Adjusted Diluted earnings (income) per share (EPS) is computed by dividing Adjusted Net Income by the weighted average number of common shares outstanding plus the effect of dilutive potential common shares outstanding during the

3

period using the treasury stock method. Dilutive potential common shares include stock purchase warrants and contingently issuable shares attributable to the earn-out consideration.

Adjusted EBITDA, Adjusted Net Income, Adjusted Basic EPS, and Adjusted Diluted EPS 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 Adjusted EBITDA, Adjusted Net Income, Adjusted Basic EPS, and Adjusted Diluted EPS rather than net income (loss), which is the nearest GAAP equivalent of Adjusted EBITDA and Adjusted Net Income, or Basic EPS and Diluted EPS, which is the nearest equivalent to Adjusted Basic EPS and Adjusted Diluted EPS. These limitations include that the non-GAAP financial measures: (i) exclude depreciation and amortization, and although these are non-cash expenses, the assets being depreciated may be replaced in the future; (ii) do not reflect interest expense, or the cash requirements necessary to service interest on debt, which reduces cash available; (iii) do not reflect the provision for or benefit from income tax that may result in payments that reduce cash available; (iv) exclude non-recurring items (i.e., the extinguishment of debt); and (v) 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.

SECOND QUARTER 2022 EARNINGS PRESENTATION August 16, 2022 1 JanusIntl.com

2 FORWARD LOOKING STATEMENTS Certain statements in this communication, including the estimated guidance provided under “2022 Outlook” 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 “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’s 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’s reports filed with the 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’s ability to compete therein; (iii) litigation, complaints, and/or adverse publicity; (iv) cyber incidents or directed attacks that could result in information theft, data corruption, operational disruption and/or financial loss; and (v) 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 Quarterly Report on Form 10-Q, as updated from time to time in amendments and its subsequent filings with the SEC.

3 Non-GAAP Financial Measures In this presentation 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. Adjusted EBITDA, and Adjusted Net Income, Adjusted Basic EPS, and Adjusted Diluted EPS 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 Adjusted EBITDA, and Adjusted Net Income, Adjusted Basic EPS, and Adjusted Diluted EPS 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, Adjusted EBITDA, and Adjusted Net Income, Adjusted Basic EPS, and Adjusted Diluted EPS 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 Net Income is defined as net income plus the corresponding tax-adjusted add-backs shown in the Adjusted EBITDA reconciliation. Adjusted Basic earnings (income) per share (EPS) is computed by taking Adjusted Net Income divided by the weighted average number of shares of common stock outstanding during the period. Adjusted Diluted earnings (income) per share (EPS) is computed by dividing Adjusted Net Income by the weighted average number of common shares outstanding plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include stock purchase warrants and contingently issuable shares attributable to the earn-out consideration. Adjusted EBITDA, and Adjusted Net Income, Adjusted Basic EPS, and Adjusted Diluted EPS 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 Adjusted EBITDA, and Adjusted Net Income, Adjusted Basic EPS, and Adjusted Diluted EPS rather than net income (loss), which is the nearest GAAP equivalent of Adjusted EBITDA and Adjusted Net Income, or Basic EPS and Diluted EPS, which is the nearest equivalent to Adjusted Basic EPS and Adjusted Diluted EPS. These limitations include that the non-GAAP financial measures: (i) exclude depreciation and amortization, and although these are non-cash expenses, the assets being depreciated may be replaced in the future; (ii) do not reflect interest expense, or the cash requirements necessary to service interest on debt, which reduces cash available; (iii) do not reflect the provision for or benefit from income tax that may result in payments that reduce cash available; (iv) exclude non-recurring items (i.e., the extinguishment of debt); and (v) 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.
