Dollar General turned in a stronger-than-expected second quarter, showing it can grow both sales and profitability in a retail backdrop where incumbents like Target are flailing. Revenue rose 5.1% to $10.7 billion, fueled by continuous same-store sales growth and new store openings, and earnings per share climbed 9.4% to $1.86. Operating profit increased 8.3% as tighter inventory control and lower shrink boosted margins, highlighting how the discounter's multiple initiatives allow it to expand margins while pulling in more shoppers across income levels.
