Earnings Beat Fuels Quality Score This move places the retailer in the top 10th percentile of stocks for fundamental strength, following a fiscal first-quarter report where it beat both earnings and revenue estimates. The sharp rise in Costco’s quality ranking—which evaluates a company’s “operational efficiency and financial health” based on historical profitability —directly reflects its first quarter performance. The retailer reported revenue of $67.31 billion, topping analyst estimates of $67.14 billion. Adjusted earnings per share reached $4.50, beating the projected $4.27. Fundamental strength was further evidenced by an 8.2% year-over-year increase in net sales and a 6.4% rise in total comparable sales. Costco exited the quarter with approximately $16.22 billion in cash, validating the high operational efficiency score. It maintains a weaker price trend over the short, medium, and long terms, with a moderate value ranking. Additional information is available here.

The company recently filed a lawsuit against the Donald Trump administration, challenging tariffs imposed under the International Emergency Economic Powers Act (IEEPA) as unlawful and seeking a full refund. To mitigate the impact of these levies, Costco is increasing production of its Kirkland Signature brand. Despite the uncertain trade environment, the retailer's ability to deliver a “beat-and-raise” quarter has solidified its reputation for operational excellence.
