Bob LaFleur -- Senior Vice President, Investor Relations

Good morning, and thank you for joining us today to discuss Dollar Tree's second-quarter results. With me today are Dollar Tree's chairman and CEO, Rick Dreiling; and CFO, Jeff Davis. Before we begin, I would like to remind everyone that some of the remarks that we will make today are about the company's expectations, plans and future prospects and are considered forward-looking statements under the Safe Harbor provision of the Private Securities Litigation Reform Act of 1995. These statements are subject to risks and uncertainties which could cause actual results to differ materially from those contemplated by our forward-looking statements.

For information on the risks and uncertainties that could affect our actual results, please see the Risk Factors, Business, and Management's Discussion and Analysis of Financial Condition and Results of Operations sections in our annual report on Form 10-K, filed on March 10, 2023, our Form 10-Q for the most recently ended fiscal quarter, our most recent press release and Form 8-K and other filings with the SEC. We caution against reliance on any forward-looking statement made today, and we disclaim any obligation to update any forward-looking statements, except as required by law. Also during this call, we will discuss certain non-GAAP financial measures. Reconciliations of these non-GAAP items to the most directly comparable GAAP financial measures are provided in today's earnings release available on the IR section of our website.

These non-GAAP measures are not intended to be a substitute for GAAP measures. Unless otherwise stated, we will refer to our financial results on a GAAP basis. Additionally, unless otherwise stated, all comparisons discussed today for the second quarter of fiscal 2023 are against the same period a year ago. Please note that a supplemental slide deck outlining selected operating metrics is available on the IR section of our website.
