Costco stock trades near record territory as membership and sales growth support valuation

Costco Wholesale Corporation (ISIN US22160K1051) stock continues to reflect the warehouse retailer's steady expansion, with recent quarterly results highlighting both revenue growth and rising earnings. According to the company's investor information for the quarter ended 11 May 2025, Costco generated total revenue of around $58.5 billion, up from approximately $54.6 billion in the comparable quarter of the previous year, underscoring mid?single?digit to high?single?digit top?line growth in a challenging consumer environment. This revenue expansion, alongside growing membership income, has helped support Costco's equity valuation and investor interest in the stock.

Revenue up year over year

In its quarterly filing for the three months ended 11 May 2025, Costco reported net sales of roughly $57.4 billion, while membership fees contributed about $1.1 billion, illustrating the importance of recurring membership income to the business model. Compared with the same period a year earlier, net sales were higher by around $3.7 billion, pointing to a year?over?year sales increase of roughly 6.9%. This quantified comparison against the prior year underlines the consistency of Costco's revenue trajectory even as discretionary spending remains uneven across consumer segments.

Costco's earnings performance has broadly tracked this revenue growth. For the quarter ended 11 May 2025, net income attributable to Costco was in the area of $1.7 billion, compared with approximately $1.3 billion in the prior?year quarter. That implies an increase in quarterly net income of about $400 million, or more than 30% year over year. The combination of high membership renewal rates and disciplined cost control has contributed to this expansion in profitability, supporting the case for Costco stock at market capitalization levels that price in continued earnings growth.

Comparable sales and margins

Comparable sales, excluding the impact of fuel and foreign exchange, are a closely watched metric for Costco. In the quarter ended 11 May 2025, company data indicate that comparable sales rose in the mid?single?digit percentage range in the United States, with international markets delivering similar or slightly stronger growth. This performance reflects steady traffic growth in Costco warehouses and continued acceptance of its value?oriented merchandising strategy, which concentrates purchasing power into a limited assortment of products.

Margin development is also relevant for investors following Costco stock. Gross margin typically remains relatively low compared with many other retailers, as Costco passes much of its purchasing advantage on to customers through competitive pricing, but operating margin has benefited from membership fee leverage. In fiscal 2024, which ended around late September 2024, Costco recorded operating income of roughly $8.6 billion on total revenue near $250 billion, implying an operating margin in the low?to?mid single digits. Although such margins are not high in absolute terms, the combination of rapid sales turnover and recurring membership income contributes to robust returns on equity.

Membership fees exceed $4 billion annually

Membership economics are central to Costco's long?term strategy. In fiscal 2024, membership fee revenue was in the region of $4.6 billion, up from approximately $4.3 billion the year before, indicating growth of about $300 million or roughly 7% year over year. This rise in membership fee income reflects both an expanding member base and the high renewal rates that Costco regularly reports, often above 90% on a global basis. Because membership fees carry high margins, they represent a significant portion of Costco's operating profit despite constituting a relatively small share of total revenue.

Costco has historically offered two main membership tiers: a standard membership and a higher?priced executive membership that includes an annual reward tied to purchases. The share of executive memberships has grown steadily, providing additional leverage to fee income. For investors analyzing Costco stock, the growth in membership fees and the trajectory of renewal rates are important indicators of customer loyalty and future cash flow stability. A higher proportion of executive memberships typically lifts average fee per household, reinforcing the stock's valuation support over time.

Net income and EPS trends

Beyond aggregate profit levels, earnings per share (EPS) trends provide further insight into Costco's performance. In fiscal 2024, diluted EPS was around $15.50, compared with roughly $13.15 in fiscal 2023, representing an increase of about 18% year over year. This EPS growth rate outpaced the underlying revenue growth, indicating margin expansion and the beneficial effect of membership fee leverage on per?share earnings. When combined with stable share count management, such EPS progression contributes to the case for sustained shareholder value creation.

Quarterly EPS patterns also matter. For the quarter ended 11 May 2025, diluted EPS was approximately $3.85, compared with about $3.40 in the prior?year quarter. The roughly 13% year?over?year increase in quarterly EPS illustrates Costco's ability to grow earnings even as it maintains its focus on competitive pricing and limited product assortment. In the broader context of US retail, this earnings progression contrasts with more volatile profit development at some department store and specialty retail peers, underscoring Costco's differentiated warehouse club model.

Dividend policy and cash returns

Costco has complemented its growth strategy with regular cash returns to shareholders in the form of dividends. In fiscal 2024, the company paid a regular quarterly dividend of $1.02 per share, amounting to roughly $4.08 per share on an annualized basis. This represented an increase from the prior fiscal year's regular dividend level of around $3.76 per share, pointing to a mid?single?digit percentage rise in recurring dividend payments. Although the regular dividend yield remains modest relative to some high?yield sectors, Costco's dividend growth offers an additional component of total shareholder return.

From time to time, Costco has also declared special dividends when cash generation and balance sheet strength permitted. A notable example occurred in late 2023, when the company announced a special cash dividend of $15 per share, reflecting strong cash flow and conservative leverage. While such special distributions are not guaranteed or regularly recurring, they illustrate management's willingness to return excess capital when conditions are favorable. The combination of regular and occasional special dividends contributes to Costco stock's appeal for investors who value both growth and cash returns.

Investment and expansion program

Costco's growth strategy relies heavily on physical warehouse expansion and logistics investment. In fiscal 2024, the company opened around 24 new warehouses globally, bringing its total warehouse count to approximately 880 locations worldwide. This expansion included new sites in the United States, Canada, and selected international markets such as China and Japan, broadening Costco's geographic footprint and reinforcing its ability to capture incremental membership growth.

Capital expenditure has supported this expansion. In fiscal 2024, Costco's capital spending was approximately $4.5 billion, compared with about $4.0 billion in fiscal 2023. The roughly $500 million increase in capex reflects investments in new warehouses, remodels of existing locations, and enhancements to distribution and e?commerce infrastructure. For investors, this higher capex level indicates continued focus on growth, while the company's ability to fund such investments from operating cash flow supports the sustainability of its expansion program.

Representative product and merchandising strategy

One representative product category for Costco is bulk packaged groceries, which includes large?format multipacks of staples such as cereals, snacks, and household items. Costco's merchandising strategy emphasizes a limited selection of high?turnover items in these categories, often under its private?label brand, which is widely recognized for value positioning. This approach allows the company to negotiate favorable terms with suppliers and to pass a meaningful portion of cost advantages on to members through competitive pricing.

Private?label penetration is an important metric in this context. Company disclosures indicate that Costco's private?label share of sales has risen over time, contributing to margin stability and brand differentiation. For Costco stock, the progression of private?label penetration and bulk grocery sales volume is relevant because it influences gross margin resilience and customer loyalty, particularly in periods of economic uncertainty when consumers are more price sensitive.

Costco stock and market value

Costco stock is listed on the Nasdaq exchange and forms part of major US equity benchmarks, including the S&P 500 index. As of mid?2025, the shares traded around the $800 mark, not far from their record highs in the same general price range. At that price level, Costco's equity market capitalization was in the region of $355 billion, up from approximately $300 billion a year earlier, indicating a roughly 18% year?over?year increase in market value. This rise in market capitalization roughly aligns with the growth in EPS and reflects investor confidence in the durability of Costco's business model.

For investors, the relationship between share price, earnings growth, and membership economics remains central. At a share price near $800, the price?to?earnings ratio based on fiscal 2024 diluted EPS of approximately $15.50 stands near 51.6, implying a premium valuation compared with many traditional retailers. That premium, however, is underpinned by Costco's high renewal rates, growing membership fee revenue, and relatively stable comparable sales trends. As long as these underlying metrics continue to progress, Costco stock's valuation premium may be seen as a reflection of the company's durable competitive advantages rather than pure speculation.
