Shares of the membership-based warehouse retailer gained approximately 1% during Thursday’s pre-market trading following the company’s announcement of May revenue totaling $24.01 billion, representing a 14.5% increase from the previous year’s figure of $20.97 billion.

This performance extends the momentum from a robust third-quarter showing for fiscal 2026, which concluded on May 10 and delivered 11.6% revenue growth. The quarter produced net earnings of $2.19 billion, translating to diluted earnings per share of $4.93.
Throughout the initial 39 weeks of the ongoing fiscal year, total revenue has climbed to $221.19 billion — representing a 10% expansion versus the comparable timeframe in the previous year.
Same-store sales metrics, which measure performance at locations operational for a minimum of one year, advanced 12.5% during May. Domestic operations remained the primary growth engine for this performance.
Online channels delivered particularly strong results, with e-commerce revenue expanding 21.1% throughout the month. The digital platform has emerged as a recurring strength for Costco as an increasing number of members allocate portions of their purchases to the company’s website.
A noteworthy product introduction: the retailer launched O Positiv Health’s URO Vaginal Probiotic exclusively across 235 physical locations and through Costco.com. While modest in scale, this initiative illustrates the company’s strategic expansion into premium wellness offerings designed to enhance member loyalty.
Fuel sales contributed significantly to third-quarter performance, with unprecedented gasoline volumes driving revenue gains. However, elevated fuel sales typically result in margin compression, a dynamic that investors continue to monitor closely.
Analyst Reservations Persist Despite Growth
Notwithstanding the impressive figures, Wall Street sentiment remains mixed. The primary concern centers on valuation — the stock currently commands the highest price multiple among large-capitalization consumer goods retailers.
Membership expansion has exhibited some slowing, which carries substantial implications given that subscription fees constitute a critical profit driver for the business. Any weakness in renewal percentages would signal potential challenges to the underlying business framework.
Margin pressure across core merchandise categories including groceries, consumer electronics, and apparel represents an additional concern that analysts have emphasized in recent commentary.
Year-to-date, shares have appreciated roughly 12%, outperforming both Walmart and BJ’s Wholesale Club. While this relative strength demonstrates investor confidence, it simultaneously elevates valuation concerns for certain market observers.
Wall Street’s Current Stance
Among 24 analysts who have issued ratings over the past three months, 16 recommend Buy, seven advise Hold, and one suggests Sell — producing a Moderate Buy consensus.
The mean price objective stands at $1,104.95, indicating potential appreciation of approximately 15% from present trading levels.
Optimistic analysts forecast revenue reaching as high as $376.8 billion with net income approaching $12.6 billion by 2029. An alternative valuation framework establishes fair value at $1,048, implying roughly 9% upside potential.
Analyst consensus anticipates long-term revenue of $329 billion by 2028, accompanied by projected earnings of $10.4 billion.
Investors will next focus on the company’s complete fiscal year financial results, as monthly sales reports continue to be released throughout the remainder of 2026.
