DOLLAR TREE, INC.

Our management has carried out, with the participation of our Chief Executive Officer and Chief Financial Officer, an evaluation of the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (“Exchange Act”) as of the end of the period covered by this report. Based upon this evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that, as of May 2, 2026, our disclosure controls and procedures were designed and functioning effectively to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and (ii) accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding disclosure.

In fiscal 2024, we began a phased implementation of a new warehouse management system which we expect to complete over the next several years. As of May 2, 2026, we have converted six distribution centers to the new system, including two converted during the first quarter of fiscal 2026. We have made changes to our internal control over financial reporting to align with the functionality and updated processes associated with the new system.

There were no other changes in our internal control over financial reporting during the fiscal quarter ended May 2, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
