Greetings, and welcome to the TopBuild First Quarter 2021 Earnings Call. [Operator Instructions] I'll now turn the call over to Ms. Tabitha Zane, Vice President of Investor Relations. Thank you. You may begin. Tabitha Zane -- Vice President of Investor Relations Thank you, and good morning. On the call today are Robert Buck, President and Chief Executive Officer; and John Peterson, Chief Financial Officer. We have posted senior management's formal remarks and a PowerPoint presentation that summarizes our comments on the Investor Relations section of our website, at topbuild.com. Many of our remarks will include forward-looking statements, which are subject to known and unknown risks and uncertainties, including those set forth in this morning's press release as well as in the company's filings with the SEC. The company assumes no obligation to update or supplement forward-looking statements that become untrue because of subsequent events. Please note that some of the financial measures to be discussed on this call will be on a non-GAAP basis. The non-GAAP measures are not intended to be considered in isolation or as a substitute for results prepared in accordance with GAAP. We have provided a reconciliation of these financial measures to the most comparable GAAP measures in a table included in today's press release and in the presentation accompanying this call.
