Costco Wholesale announced fiscal fourth-quarter net sales of $93.9 billion, up 11.3% from $86.16 billion a year earlier, while comparable sales increased 9.4%. The reported net sales were below Benzinga Pro’s $94.82 billion estimate and Visible Alpha’s $94.85 billion forecast. Costco’s full earnings report, scheduled for September 24, will disclose membership fees, total revenue, expenses, earnings and additional guidance. Investors are expected to focus on membership growth, comparable sales, margins, fuel prices and consumer spending, with options pricing implying a potential 3% share-price move by the end of the week.
