Costco Wholesale (US22160K1051) stock is trading close to $945 as of August 31, 2026, with investors weighing that level against the company’s latest fiscal 2026 third-quarter earnings and a premium valuation multiple.
In its fiscal third quarter for the 12 weeks ended May 10, 2026, Costco reported net sales of $69.15 billion and diluted earnings per share of $4.93, figures that now anchor many analysts’ views on the stock.
For retail investors, the core question is how Q3 2026 performance and the current price near $945 compare with consensus earnings expectations and price targets that sit above the $1,050 mark.
Q3 2026 earnings detail and growth
Per recent coverage of Costco’s fiscal third-quarter results for the period ended May 10, 2026, net sales reached $69.15 billion, representing year-over-year growth of 11.6 percent from the same quarter a year earlier.
Reported diluted EPS of $4.93 in that quarter edged below one cited consensus estimate of $4.94, a shortfall of $0.01, while still aligning broadly with expectations that called for earnings in the high $4 range.
Another detailed earnings overview notes that total quarterly revenue was $70.53 billion, compared with analyst estimates of $70.12 billion, indicating that Costco exceeded that particular top-line consensus by $0.41 billion while posting the same $4.93 EPS figure and a net margin in the low single digits.
Across these Q3 snapshots, the company’s sales performance against expectations was modestly positive in some views, while EPS was essentially in line, reflecting steady profitability even as operating costs and investment in growth remain significant.
Costco’s comparable sales trends also support the growth narrative: U.S. comparable sales excluding gasoline grew by 6.8 percent in the fiscal third quarter, underscoring that core membership-driven traffic and basket size continue to expand.
From an earnings-power perspective, one consensus view points to anticipated full-year EPS of 20.42 for the current fiscal year, with the next fiscal year’s EPS estimate raised slightly to 22.51 in recent updates, suggesting mid-single-digit earnings growth expectations on top of the latest quarterly performance.
Valuation, price targets, and trading range
The current trading level around $945 sits within a broader range that has seen Costco stock reach a 52-week high of 1,096.50, with recent commentary highlighting that the shares are down 13.8 percent from that peak as of early September 2026.
According to one valuation-focused analysis, Costco is trading at 46 times this year’s earnings estimates at the recent $945 price, indicating a price-to-earnings multiple well above the broader market and emphasizing how much future growth is already priced into the shares.
Analyst consensus compiled by one market-data overview shows a Moderate Buy rating on Costco with an average price target of 1,059.53, giving the stock roughly 12 percent potential upside from a 945.47 reference price if that consensus target were reached.
A separate analyst roundup points to a similar Moderate Buy view with an average price target of 1,087.20, implying a 15 percent gap between the current price zone around $945 and that higher target level.
Some individual price-target adjustments have reinforced this premium stance: following Q3 results, one firm raised its price target to 1,011 from 977 while retaining a Hold rating, and another lifted its target to 1,200 from 1,185 while keeping a Buy rating and slightly increasing its fiscal 2027 EPS view by $0.10.
These revisions suggest that while the stock’s valuation is rich at 46 times current-year EPS estimates, analysts remain comfortable projecting further earnings expansion that could support price levels above $1,050 in the medium term.
For investors, the quantified comparison between the roughly $945 trading price, the 1,059.53 to 1,087.20 consensus target range, and the 1,200 upper-tier target highlights the balance between near-term premium valuation risk and longer-term growth expectations.
Earnings momentum and international expansion
Beyond the headline Q3 numbers, recent analysis of Costco’s earnings trajectory emphasizes that consensus EPS estimates have remained stable for the current year at 20.42, while next fiscal year estimates nudged higher to 22.51 over the past month.
This incremental upward revision, even by a penny, signals that analysts see room for continued operating leverage as membership fees, higher-margin ancillary services, and international warehouse growth contribute to overall profitability.
Costco’s international operations are increasingly cited as a potential major driver of long-term growth, with markets in Asia and Europe offering room for both membership expansion and higher sales per warehouse compared to earlier stages of its U.S. growth curve.
In that context, the Q3 2026 performance with revenue above some consensus marks and solid U.S. comparable sales provides a base from which international contributions can become a larger share of total sales over the coming years.
Investors tracking earnings momentum will note that the company’s return on equity around 28 percent in the latest quarter reflects efficient use of capital despite heavy investment in new warehouses and infrastructure.
For long-term holders, the combination of double-digit revenue growth in Q3 2026, mid-single-digit expected EPS growth year over year, and high return on equity helps justify at least part of the current premium price-to-earnings multiple.
Dividend and shareholder returns
Costco’s shareholder-return profile includes a regular quarterly dividend that was most recently cited at 1.47 per share, corresponding to an annualized payout of 5.88 and a dividend yield of 0.6 percent at the recent trading level.
The ex-dividend date for that payment fell on July 24, with the dividend paid on August 7 to shareholders of record as of the July cutoff, reinforcing the company’s track record of consistently returning cash to investors even as it continues to invest heavily in growth.
While a 0.6 percent yield is modest compared to many income-oriented stocks, Costco’s dividend policy has historically been complemented by occasional special dividends that further enhance long-term total return for shareholders.
In evaluating the stock’s total-return potential, investors can compare the 0.6 percent dividend yield and the consensus price-target upside in the 12 to 15 percent range with the 46 times earnings valuation multiple, which requires durable earnings growth to sustain.
This trade-off underscores why many analyses urge investors to balance enthusiasm for Costco’s business model against the risks of paying a high multiple during periods when earnings beat or miss versus consensus is measured in pennies per share.
Costco membership and core warehouse proposition
Costco’s business model centers on its membership-based warehouse clubs, offering members access to bulk merchandise, private-label goods, and ancillary services at pricing designed to deliver clear value relative to traditional retail formats.
Membership fees are a critical component of the company’s earnings structure, contributing a stable, high-margin revenue stream that supports operating income and allows Costco to keep merchandise margins relatively low.
The company’s private-label Kirkland Signature line, which spans categories from groceries and household products to apparel and consumer goods, plays a key role in reinforcing member loyalty and driving repeat purchases at attractive margins.
In the fiscal third quarter of 2026, U.S. comparable sales growth excluding gasoline at 6.8 percent shows how the membership and value proposition are translating into tangible traffic and sales gains in Costco’s largest market.
Ancillary services such as fuel stations, pharmacies, optical centers, and travel offerings further deepen the relationship with members and add diversified revenue streams that can buffer cyclical swings in discretionary spending.
For many investors, the strength of this membership-centric model and its demonstrated ability to produce double-digit sales growth in Q3 2026 is a central justification for the stock’s valuation metrics and analyst price targets.
Representative product: Kirkland Signature consumer goods
One representative element of Costco’s merchandise strategy is its Kirkland Signature branded consumer goods, which are prominently featured across warehouses and online channels as an alternative to national brands.
Kirkland Signature products typically offer a balance of quality and price that helps Costco differentiate its assortment and build member trust, whether in staple categories like paper goods and cleaning supplies or in higher-value areas such as electronics and specialty foods.
By emphasizing Kirkland Signature, Costco can capture higher margins than on pure third-party branded products while still delivering a compelling value proposition, reinforcing the company’s overall pricing power and member retention.
The success of Kirkland Signature also provides a tangible example of how Costco leverages scale, sourcing relationships, and data on member preferences to create products that support both revenue growth and profitability.
Stock level and investor takeaway
Costco stock, listed on Nasdaq under the ticker COST, is trading around $945 as of August 31, 2026, based on recent market-data snapshots for the latest completed U.S. trading session.
At that level, the shares sit below the 52-week high of 1,096.50 but still command a valuation of 46 times current-year earnings estimates, a combination that places the stock in a premium bracket relative to many peers and underscores the importance of sustained earnings and sales growth for long-term investors.
