Special Note Regarding Forward-Looking Statements and Information

This Quarterly Report on Form 10-Q, other periodic reports filed by us under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and other written or oral statements made from time to time by our management contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Terms such as “may,” “intend,” “might,” “will,” “should,” “could,” “would,” “expect,” “believe,” “estimate,” “anticipate,” “predict,” “project,” “potential,” or the negative of these terms, and similar expressions often signify forward-looking statements. Forward-looking statements are subject to risks and uncertainties that are beyond our control, and because they also relate to the future, they are likewise subject to inherent uncertainties and other factors that may cause actual results to differ materially from the views, beliefs, and projections expressed in such statements. Further, any forward-looking statement speaks only as of the date on which it is made, and we undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which it is made or to reflect the occurrence of anticipated or unanticipated events or circumstances. Factors that may cause actual results to differ materially from those expressed or implied by the forward-looking statements include, but are not limited to, the following:

•cyclicality in residential and commercial construction markets;

•general business, economic, and financial market conditions, the level of new home sales and construction activity, geopolitical conflicts, trade disputes, inflationary pressures, capital markets volatility, and declines in consumer confidence;

•severe weather and climate conditions;

•seasonality of our business and its impact on demand for our products;

•volatility in the prices for the products we purchase and the costs required to operate our business;

•laws and regulations governing our operations;

•risks related to our current indebtedness, including with respect to elevated interest rates on our variable indebtedness, and our ability to obtain financing in the future;

•threats from terrorism, violence, uncertain political conditions, and geopolitical conflicts with Iran as well as the ongoing conflict between Russia and Ukraine and other disruptions in the Middle East; and

•risks related to other factors discussed in our Annual Report on Form 10-K and in this Quarterly Report on Form 10-Q.

You should not place undue reliance on any forward-looking statements, which speak only as of the date made. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible to predict all of them. We assume no obligation and do not intend to update or revise any forward-looking statements that are made from time to time, either as a result of future developments, new information or otherwise, except as may be required by law.

Comparisons of results for current and any prior periods are not intended to express any future trends, or indications of future performance, unless expressed as such, and should only be viewed as historical data.
