Dollar Tree's Chief Financial Officer (CFO) is set to depart next year, as the company raises its full-year sales guidance following a rebound in its stock price. The retailer's shares increased by 2% after reporting solid third-quarter earnings and adjusting its fiscal year 2024 outlook. Analysts remain cautious, questioning whether this marks the beginning of a turnaround or simply a dip-buying opportunity. Amidst these changes, Dollar Tree continues to face challenges from competitors like Walmart and Dollar General, particularly in discretionary goods. The CEO noted that core customers are experiencing significant financial pressure, which is affecting their shopping behavior. In a related industry move, Dollar General is testing same-day delivery services as it seeks to compete more effectively with Walmart.
