Costco Wholesale stock steadies ahead of key earnings and reflects strong sales growth

Costco Wholesale stock (ISIN US22160K1051) is trading near USD 890 on the Nasdaq as of September 20, 2026, leaving the membership warehouse giant valued at close to USD 400 billion and setting the stage for a closely watched earnings release later this week. As Mitrade reported on September 20, 2026, Costco will present its fourth-quarter fiscal 2026 results on September 24, with investors already informed that net sales for that quarter rose 11.3 percent year over year to USD 93.9 billion.

Fourth-quarter fiscal 2026 sales already point higher

For the fourth fiscal quarter ended August 30, 2026, Costco previously disclosed net sales of USD 93.9 billion, an 11.3 percent increase compared with the same quarter a year earlier, underlining the continued expansion of the warehouse retailer’s top line. According to Mitrade, excluding the impact of gasoline prices and foreign exchange fluctuations, total company comparable sales in that quarter increased by 6.7 percent, while comparable sales for digital channels jumped 19.8 percent.

This mix of double-digit revenue growth and high-teens digital comparable sales illustrates how Costco is leveraging both its physical warehouse footprint and online channels to drive higher member spending. For investors, the quantified growth of 11.3 percent in net sales and 6.7 percent in comparable sales provides a concrete benchmark to compare against the earnings and margin figures that will be reported on September 24, 2026.

Upcoming earnings date anchors investor focus

The forthcoming results release is now a central calendar event for the stock. As Mitrade outlined on September 20, 2026, Costco will report its fourth-quarter fiscal 2026 financial results after market close on September 24 and hold its earnings conference call at 5:00 p.m. Eastern Time. Other market commentaries, including updates highlighted by Investopedia on September 20, 2026, also flag the Costco release as one of the key events in the week’s earnings calendar.

The focus of this earnings report, according to Mitrade, will be on membership fee revenue, renewal rates, merchandise gross margins, operating expenses and earnings per share. With net sales for the quarter already known and showing 11.3 percent growth, the market now wants to see how much of that topline expansion translates into profit growth and whether higher operating costs or investments in delivery partnerships exert pressure on margins.

Valuation, analyst expectations and growth backdrop

Recent data from stock portals show Costco trading at a price to earnings ratio around the mid-40s, which is above many broad market averages and reflects investors’ willingness to pay a premium for the company’s membership model and consistent cash generation. For example, MarketBeat lists a trailing P/E ratio of 45.04 and notes that Costco’s consensus price target stands at USD 1,052.65, implying about 17.6 percent upside from a spot price referenced at USD 895.31.

In terms of analyst sentiment, MarketBeat reports that Costco Wholesale currently carries a consensus rating of Moderate Buy, based on a mix of buy, hold and a very small number of sell recommendations, with an average rating score of 2.62 across dozens of analysts. Earnings for Costco are expected to grow by around 10.19 percent in the coming year, according to the same overview, with consensus forecasting earnings per share rising from USD 20.42 to USD 22.50.

These expectations tie directly into the upcoming fourth-quarter fiscal 2026 results. If the reported earnings per share and margin trajectory align with or exceed the projected 10.19 percent earnings growth, the valuation premium of a roughly 45 times trailing earnings multiple may be seen as justified by many investors. Conversely, any sign that margins are being squeezed or that membership fee growth is slowing could lead analysts to revisit their price targets and rating stance.

Fiscal 2025 context and long-term membership economics

Beyond the imminent quarter, Costco’s recent fiscal-year performance provides additional context for the stock’s high valuation and strong investor interest. According to a business model analysis that cites Costco’s FY2025 annual report, The Strategy Story reports that net sales in fiscal 2025 reached USD 269.91 billion, an increase of USD 20.29 billion or 8 percent compared with the prior fiscal year, while net income rose 10 percent to USD 8.10 billion.

In the same fiscal 2025 period, Costco generated USD 30.03 billion of gross margin on USD 269.91 billion of net sales, corresponding to a gross margin rate of 11.12 percent, and operating cash flow increased to USD 13.34 billion from USD 11.34 billion, a rise of roughly 18 percent. Membership fees of USD 5.32 billion in fiscal 2025 compared with net income of USD 8.10 billion, underlining the importance of recurring membership revenue to the company’s profitability and the resilience of its model in different economic environments, as highlighted by The Strategy Story.

These fiscal 2025 figures are historical rather than current, but they frame the expectations around the fourth-quarter fiscal 2026 release. Investors will compare the newly reported numbers against the fiscal 2025 baseline to evaluate whether revenue growth is sustaining at or above the 8 percent level, whether net income growth remains around 10 percent or improves, and how membership fee trends evolve beyond the USD 5.32 billion reported in the last full fiscal year.

Risks and points to watch in the upcoming report

While the topline numbers for the fourth-quarter fiscal 2026 period are strong, there are several key risks and counter-factors that the market is likely to scrutinize when Costco reports full results. According to Mitrade, merchandise gross margins and operating expenses are crucial areas that could temper the positive impact of strong sales growth if cost pressures rise faster than expected.

Another factor is the performance of Costco’s delivery partnerships and digital channels. The same fourth-quarter fiscal 2026 disclosure cited by Mitrade highlighted a 19.8 percent increase in comparable sales for digital channels, which is substantially above the 6.7 percent total comparable sales growth. This divergence suggests that digital and delivery-driven sales are becoming a larger share of Costco’s business, potentially affecting cost structures and margins in different ways than traditional in-warehouse sales.

For investors, the interplay between these factors will be central: strong revenue growth of 11.3 percent in the fourth fiscal quarter and a historical net income growth of 10 percent in fiscal 2025 set a high bar, but sustained margin discipline and efficient operating cost management must accompany that growth for Costco Wholesale stock to continue justifying a trailing P/E near 45 and a consensus price target more than 15 percent above recent trading levels.
