United Parcel Service (UPS) reported first-quarter earnings of $3.05 per share, outpacing estimates of $2.87, along with revenues of $24.4 billion. However, the market reacted negatively, causing shares to plunge over 3%, primarily due to concerns about declining package volumes and inflationary pressures. In response to its strong performance, UPS plans to double its share buyback program to $2 billion while maintaining an optimistic annual revenue forecast of approximately $102 billion.
