FORWARD LOOKING STATEMENTS This presentation contains “forward looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by words such as: “assume,” “believe,” “could,” “estimate,” “expect,” “guidance,” “may,” “outlook,” “forecast,” “intend,” “project,” “anticipate,” “should,” “plan” and similar references to future periods. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. Our actual results and financial condition may differ materially from those indicated in the forward-looking statements. Therefore, you should not rely on any of these forward-looking statements. Important factors that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements include, among others, the following: the impact of the COVID-19 pandemic and related measures taken by governmental or regulatory authorities to combat the pandemic, including the impact of the pandemic and these measures on the economies and demand for our products in the states where we sell them, and on our customers, suppliers, labor force, business, operations and financial performance; unpredictable weather and macroeconomic factors that may negatively impact the repair and remodel and new construction markets and the construction industry generally, especially in the state of Florida and the western United States, where the substantial portion of our sales are currently generated, and in the U.S. generally; changes in raw material prices, especially for aluminum, glass and vinyl, including, price increases due to the implementation of tariffs and other trade-related restrictions; our dependence on a limited number of suppliers for certain of our key materials; our dependence on our impact-resistant product lines, which increased with our acquisition of a 75% ownership stake in Eco Enterprises, LLC (the “Eco Acquisition”), and contemporary indoor/outdoor window and door systems, and on consumer preferences for those types and styles of products; the effects of increased expenses or unanticipated liabilities incurred as a result of, or due to activities related to, our acquisition of NewSouth and our Eco Acquisition; our level of indebtedness, which increased in connection with our acquisition of NewSouth, and increased further in connection with our Eco Acquisition; increases in bad debt owed to us by our customers in the event of a downturn in the home repair and remodel or new home construction channels in our core markets and our inability to collect such debt; the risks that the anticipated cost savings, synergies, revenue enhancement strategies and other benefits expected from our acquisition of NewSouth and from our Eco Acquisition may not be fully realized or may take longer to realize than expected or that our actual integration costs may exceed our estimates; increases in transportation costs, including increases in fuel prices; our dependence on our limited number of geographically concentrated manufacturing facilities, which increased further due to our Eco Acquisition; sales fluctuations to and changes in our relationships with key customers; federal, state and local laws and regulations, including unfavorable changes in local building codes and environmental and energy code regulations; risks associated with our information technology systems, including cybersecurity-related risks, such as unauthorized intrusions into our systems by “hackers” and theft of data and information from our systems, and the risks that our information technology systems do not function as intended or experience temporary or long-term failures to perform as intended; product liability and warranty claims brought against us; in addition to our acquisition of NewSouth, and our Eco Acquisition, our ability to successfully integrate businesses we may acquire in the future, or that any business we acquire may not perform as we expected when we acquired it; and the other risks and uncertainties discussed under “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended January 2, 2021, and our other filings with the Securities and Exchange Commission. Any forward-looking statement made by us in this presentation is based only on information currently available to us and speaks only as of the date on which it is made. We undertake no obligation to publicly update any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise. 2

Use of Non-GAAP Financial Measures This presentation and the financial schedules include financial measures and terms not calculated in accordance with U.S. generally accepted accounting principles (GAAP). We believe that presentation of non-GAAP measures such as adjusted net income, adjusted net income per share, and adjusted EBITDA provides investors and analysts with an alternative method for assessing our operating results in a manner that enables investors and analysts to more thoroughly evaluate our current performance compared to past performance. We also believe these non-GAAP measures provide investors with a better baseline for assessing our future earnings potential. The non-GAAP measures included in this release are provided to give investors access to types of measures that we use in analyzing our results. Adjusted net income consists of GAAP net income adjusted for the items included in the accompanying reconciliation. Adjusted net income per share consists of GAAP net income per share adjusted for the items included in the accompanying reconciliation. We believe these measures enable investors and analysts to more thoroughly evaluate our current performance as compared to the past performance and provide a better baseline for assessing the Company's future earnings potential. However, these measures do not provide a complete picture of our operations. Adjusted EBITDA consists of net income, adjusted for the items included in the accompanying reconciliation. We believe that adjusted EBITDA provides useful information to investors and analysts about the Company's performance because they eliminate the effects of period-to-period changes in taxes, costs associated with capital investments and interest expense. Adjusted EBITDA does not give effect to the cash the Company must use to service its debt or pay its income taxes and thus does not reflect the actual funds generated from operations or available for capital investments. Our calculations of adjusted net income and adjusted net income per share, and adjusted EBITDA are not necessarily comparable to calculations performed by other companies and reported as similarly titled measures. These non-GAAP measures should be considered in addition to results prepared in accordance with GAAP but should not be considered a substitute for or superior to GAAP measures. Schedules that reconcile adjusted net income, adjusted net income per share, and adjusted EBITDA to GAAP net income are included in the financial schedules accompanying this release. Adjusted EBITDA as used in the calculation of the net debt-to-Adjusted EBITDA ratio, consists of our adjusted EBITDA as described above, but for the trailing twelve-month period, adjusted pursuant to the covenants contained in our credit agreements. 3
