Operator Good day, and welcome to the Yelp First Quarter 2021 Earnings Call. [Operator Instructions] Please note, this event is being recorded. I would now like to turn the conference over to James Miln, Senior Vice President of Finance and Investor Relations. Please go ahead. James Miln -- Senior Vice President of Finance & Investor Relations Good afternoon, everyone, and thanks for joining us on Yelp's First Quarter 2021 Earnings Conference Call. Joining me today are Yelp's Chief Executive Officer, Jeremy Stoppelman; Chief Financial Officer, David Schwarzbach; and Chief Operating Officer, Jed Nachman. We published a shareholder letter on our Investor Relations website and with the SEC and hope everyone had a chance to read it. We will provide some brief opening comments and then turn to your questions. Now I'll read our safe harbor statement. We'll make certain statements today that are forward-looking and involve a number of risks and uncertainties that could cause actual results to differ materially. Please note that these forward-looking statements reflect our opinions only as of the date of this call, and we undertake no obligation to revise or publicly release results of any revision to these forward-looking statements in light of new information or future events. In addition, we are subject to a number of risks that may significantly impact our business and financial results. Please refer to our SEC filings as well as our shareholder letter for a more detailed description of the risk factors that may affect our results. During our call today, we'll discuss adjusted EBITDA and adjusted EBITDA margin, which are non-GAAP financial measures. These measures should not be considered in isolation from or as a substitute for financial information prepared in accordance with generally accepted accounting principles. In our shareholder letter released this afternoon and our filings with the SEC, each of which is posted on our website, you will find additional disclosures regarding these non-GAAP financial measures as well as historical reconciliations of GAAP net income to both adjusted EBITDA and adjusted EBITDA margin.
