Costco beats earnings estimates with strong holiday sales and lawsuits over tariffs.

Costco posted stronger-than-expected fiscal first-quarter results for 2026, with revenue of $67.3 billion and earnings of $4.50 per share, surpassing forecasts. The company saw record holiday sales, including 358,000 whole pizzas sold in U.S. food courts and over 4.5 million pies in the days before Thanksgiving. Black Friday online sales hit $250 million in non-food items, a new high. Same-store sales rose 6.4%, driven by increased traffic and higher transaction sizes. Costco also filed a federal lawsuit challenging Trump-era tariffs, seeking refunds for payments made under the emergency orders. Despite the positive results, its stock dipped slightly after hours.
