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

Costco Wholesale stock has been supported in recent months by a combination of resilient membership income and steady comparable sales growth, providing investors with a clearer picture of how the warehouse-club model translates into earnings and cash generation for the company (ISIN US22160K1051). As of 31 May 2026, Costco Wholesale shares remained close to their 52-week high, underpinned by solid revenue expansion and consistent profitability according to the companys latest reported financials. For investors, the balance between membership fee stability and merchandise margin dynamics has become a central lens through which the stock is increasingly judged.

Revenue up double digits in recent fiscal period

According to Costco Wholesale investor communications for the fiscal year ended 1 September 2024, the company generated approximately $250 billion in total revenue, up around 6% from about $235 billion in the prior fiscal year, illustrating ongoing growth despite a mixed macroeconomic backdrop. This revenue base reflects both merchandise sales and membership-related income, demonstrating how the combination of high-volume, low-margin retail and recurring fee income supports Costco Wholesale stock over the long term.

In the same fiscal 2024 period, Costco Wholesale reported net income in the region of $8.0 billion, compared with roughly $7.0 billion a year earlier, representing growth of around 14% year on year and highlighting a faster rise in profitability than in top-line revenue. That spread between revenue and profit growth indicates improving operating leverage, cost discipline, and the incremental contribution of membership fees, and it feeds directly into the value investors ascribe to Costco Wholesale stock.

Costco Wholesale also disclosed diluted earnings per share for fiscal 2024 of approximately $18.00, versus around $15.00 in fiscal 2023, marking an increase of about 20% year on year. This EPS expansion outpaced revenue growth and reflects both margin improvements and the impact of capital allocation decisions such as share repurchases and special dividends over time. For shareholders evaluating Costco Wholesale stock, that degree of EPS momentum can justify a premium valuation relative to many traditional brick-and-mortar retail peers.

Membership income and margins underpin Costco Wholesale stock

Costco Wholesale operates a membership model whereby customers pay annual fees to access warehouse-club stores and online services, creating a recurring revenue stream that is particularly valuable for investors. According to the companys fiscal 2024 reporting, membership fee revenue was approximately $5.0 billion, up around 8% from roughly $4.6 billion in fiscal 2023, with the growth tied to both price increases and continuing expansion of the member base. That recurring fee contribution plays a central role in supporting the earnings profile and in reducing volatility, an important factor behind the perceived stability of Costco Wholesale stock.

Costco Wholesale reported that its overall membership renewal rate in the United States and Canada remained around 92% in fiscal 2024, while worldwide renewal rates were approximately 90%, broadly consistent with levels in the prior year. These high renewal rates underline the stickiness of the customer base and the value members perceive in the offering, providing investors with confidence that membership revenue is likely to remain resilient across economic cycles. For Costco Wholesale stock, such customer loyalty helps to mitigate cyclical risks that might otherwise weigh on a purely discretionary retail model.

On the margin side, Costco Wholesale indicated that its gross margin percentage remained in the mid-teens, with merchandise margins structurally lower than many traditional retailers due to the companys focus on rapid turnover and competitive pricing. However, operating margin has been supported by tight expense control and contributions from membership income and ancillary businesses such as gasoline sales and services. In fiscal 2024, operating income rose to approximately $10.5 billion from about $9.3 billion in fiscal 2023, an increase of around 13%, again outpacing revenue growth and signaling improved efficiency.

Representative product line and warehouse assortment

Costco Wholesale is widely known for its private-label brand Kirkland Signature, which spans grocery items, household products, and categories such as vitamins and nutritional supplements. Kirkland Signature fuels both customer loyalty and margin improvement by allowing Costco Wholesale to exercise greater control over sourcing, quality, and pricing compared with third-party branded goods. In fiscal 2024, sales of private-label merchandise, including Kirkland Signature, represented a significant share of overall revenue, contributing to the perception of Costco Wholesale stock as backed by differentiated product economics rather than solely acting as a low-price channel for external brands.

Costco Wholesale stock and market valuation

From a market perspective, Costco Wholesale stock is listed on Nasdaq under the ticker COST, and the company is part of the S&P 500 index, reflecting its scale and importance in the United States equity market. As of 31 May 2026, the companys shares traded around $820, putting Costco Wholesale near a record high and close to the top of its 52-week range of roughly $570 to $830. That positioning close to the upper end of the range indicates that investors have been willing to assign a premium valuation multiple to the earnings and cash flows generated by Costco Wholesale.

With a share price near $820 and diluted EPS of approximately $18.00 for fiscal 2024, Costco Wholesale stock has been trading at a trailing price-earnings ratio of around 45 times, substantially above the low- to mid-teens multiples often seen for broader U.S. retail indices. For investors, that high multiple reflects expectations of continued growth in membership fee revenue, store and e-commerce expansion, and ongoing operational efficiency. It also signals that any future slowdown in comparable sales or membership growth would likely be scrutinized closely by the market, as the premium valuation leaves limited room for disappointment.

Market capitalization provides another lens on the companys scale. Based on the share price around $820 and roughly 445 million diluted shares outstanding, Costco Wholesales equity value stood close to $365 billion as of 31 May 2026, placing the company among the largest global retailers by market value. For Costco Wholesale stock, this scale means broad index representation, high liquidity, and a significant investor base that includes both active managers and passive funds that track the S&P 500 and related benchmarks.
