Why is Costco Wholesale (COST) moving?

Q3 2026
▲2▼2

Costco grows sales and expands, but faces margin and regulatory pressures

  • Sales near $300B and expansion plans Costco's sales approached $300 billion with 10.2% growth, and digital and delivery expanded to 47 states. Market share gains led to a $7.5 billion plan for 33 new warehouses.

    This shows the core business is still growing strongly, which supports the stock price.

  • New ventures in healthcare and China Costco entered Medicare through SCAN Health Plan and advanced in China with JD.com, while pursuing green logistics. These moves open new revenue streams and show strategic innovation.

    These new business lines could drive future growth and diversify revenue.

  • Slowing comparable sales and membership growth Comparable sales slowed and membership fee growth decelerated to 7.3%, raising concerns about future revenue. A grocery price war loomed, threatening margins.

    Slowing key metrics and competitive pressures could hurt profitability and investor confidence.

  • Regulatory probe and margin pressures The DOJ expanded a beef-price probe to Costco, and inflation squeezed electronics margins. Kirkland oil price hikes hurt its low-price reputation, while Fed rate caution and retail selloffs added volatility.

    These issues create legal, reputational, and financial risks that could weigh on the stock.

Costco's digital and delivery surge offset by membership and margin pressures

  • Digital sales and delivery expansion Costco's digital sales surged and delivery expanded to 47 states through Uber Eats and DoorDash, boosting convenience and reaching more customers. This helped drive Q4 sales and EPS above estimates and full-year sales near $300 billion.

    This point highlights a key growth driver that is new and positive for the period.

  • Market share gains and expansion plans Costco gained market share from Kroger and announced a $7.5 billion plan to build 33 new warehouses. Ancillary businesses like gas, pharmacy, and travel also performed well, supporting overall growth.

    This point shows strategic moves that strengthen Costco's competitive position and future growth.

  • Slowing membership fee growth Membership fee growth slowed sharply to 7.3%, raising concerns about future revenue and customer loyalty. This slowdown could pressure profits if it continues.

    This point identifies a key risk that emerged during the period and could weigh on the stock.

  • Margin pressures from inflation and pricing AI-driven memory chip inflation squeezed electronics margins, and Costco doubled Kirkland motor oil prices, hurting its low-price reputation. These factors may reduce customer trust and profitability.

    This point captures specific cost and pricing challenges that could impact margins and brand perception.

Costco's Q4 Beat, Delivery Expansion, and Ancillary Strength Drive Optimism

  • Q4 Earnings Beat and Full-Year Sales Near $300B Costco reported fiscal Q4 net sales up 12% to $95.72 billion, beating estimates, with EPS up 15% to $6.57. Full-year sales reached $297.2 billion. This confirms shoppers are still spending at Costco, supporting the stock price.

    This is the core financial result that reassures investors about Costco's growth and profitability.

  • Uber Eats and DoorDash Delivery Expansion Costco expanded Uber Eats delivery from 17 to 47 states, covering nearly 600 warehouses, and launched nationwide on DoorDash. This makes Costco products available to more customers who want home delivery, boosting sales and membership appeal.

    This shows Costco is aggressively growing its digital and delivery footprint, a key driver of future sales.

  • Strong Ancillary Businesses: Gas, Pharmacy, Travel Costco's ancillary businesses delivered strong Q4 results: record gasoline volumes, nearly 20% pharmacy sales growth, and double-digit travel growth. This diversification adds steady profit and offsets weakness in other areas.

    These ancillary segments are increasingly important profit drivers and show Costco's ability to grow beyond groceries.

  • Analysts Split on Valuation Despite Strong Results Analysts are divided: some see more upside with targets up to $1,100, while others warn of slowing traffic and membership growth, with a Sell rating and $781 target. This creates uncertainty about how much growth is already priced in.

    This highlights the key debate that could cap stock gains or cause volatility, giving a balanced view.

Costco beats on sales and profit, plans bigger expansion, but margin and membership fee growth slow

  • Q4 sales and earnings beat expectations Costco reported fourth-quarter net sales up 11.3% to $93.9 billion and adjusted earnings of $6.60 per share, beating analyst forecasts. Same-store sales rose 9.4%, with online sales up 19.5%. This shows shoppers are still spending at Costco, which supports the stock price.

    This is the core new financial result that directly answers why COST is moving.

  • Costco plans $7.5 billion expansion with 33 new warehouses Costco will spend about $7.5 billion in fiscal 2027 to open 33 new warehouses, aiming for roughly 30 net new locations a year. This signals confidence in future growth and could attract investors looking for long-term expansion.

    New capital plan shows management's growth outlook, a key driver for the stock.

  • Membership fee growth slows sharply Membership fee income grew only 7.3% in the quarter, down from 14% a year ago, because the September 2024 fee increase has almost fully phased in. Since membership fees are a big part of profit, slower growth could pressure the stock.

    This is a new negative detail from the earnings report that could weigh on the stock.

  • AI memory chip inflation squeezes electronics margins Costco is absorbing higher costs for memory chips used in electronics, which pushed its gross profit margin down to 11.01% from 11.12%. This shows a real cost pressure from the AI boom that could hurt profitability if it continues.

    New cost headwind that explains margin pressure and could affect future earnings.

Costco's digital and delivery surge offsets oil-driven price pressures

  • Digital sales boom Costco's online comparable sales jumped 17.9% in August and 20.9% for the full year, far outpacing overall growth. This shows members are increasingly buying online, which lifts sales and keeps Costco competitive with Amazon and Walmart.

    Digital growth is a key new driver of demand and competitive strength.

  • Delivery expansion Costco expanded Uber Eats delivery to 47 states from 17 and added DoorDash, reaching nearly 600 warehouses. This makes Costco products available to more customers who want home delivery, boosting sales and membership appeal.

    New delivery partnerships directly expand Costco's reach and sales channels.

  • Motor oil price hike Costco doubled its Kirkland motor oil price to $57.99 and capped purchases at two per member as crude nears $100. This pressures Costco's low-price reputation and could hurt member satisfaction if energy costs keep rising.

    Rising oil costs are forcing Costco to raise prices, a new margin and pricing risk.

  • Kroger share shift Kroger lost over $12 billion in packaged goods spending to Amazon, Walmart and Costco. Costco is gaining customers from a rival, which supports sales growth and market share gains.

    Competitive gains from Kroger's weakness show Costco is winning market share.

Costco nears $300B sales, enters Medicare, faces DOJ beef probe

  • Medicare partnership opens new demand channel Costco is entering Medicare for the first time with SCAN Health Plan, offering Costco-branded Medicare Advantage and supplement plans in three states covering about 5 million enrollees. This expands services beyond groceries, potentially driving member engagement and sales of pharmacy, vision, and hearing aids.

    New business line that could add a recurring revenue stream and deepen member loyalty.

  • Sales near $300 billion with double-digit growth Costco reported fiscal 2026 net sales of $297.3 billion, up 10.2%, and August net sales rose 9.9% year-over-year. Comparable sales excluding gas and currency rose 5.6% for August and 6.6% for the full year. Bank of America reiterated a Buy rating with a $1,200 price target, citing market share gains and higher-income shoppers.

    Shows the core business remains strong and is still growing rapidly even at a huge scale.

  • DOJ expands beef price probe to Costco The Department of Justice sent letters to eight major grocers, including Costco, as part of an expanded investigation into rising retail beef prices. While no wrongdoing is alleged, the probe could lead to regulatory pressure, fines, or reputational risk, and may weigh on the stock until resolved.

    New regulatory risk that could affect costs, pricing, and investor sentiment.

  • Fed rate caution and retail sector jitters Fed Chair Warsh said the Fed has 'no tolerance' for persistent inflation and could raise rates, making defensive stocks like Costco attractive. But Walmart's weak sales triggered a retail selloff that dragged Costco down 2.2% despite its own strong results. These are short-term market moves, not changes to Costco's business.

    Explains recent price swings and the broader environment, but does not alter Costco's long-term fundamentals.

Costco faces growth slowdown and price war, but expands in China and green logistics

  • Slowing sales growth and price war Costco's June comparable sales growth slowed to 8.8% from 12.5%, and a grocery price war with Walmart and Kroger is looming. This pressured the stock, which fell over 10% from its May high.

    This explains the main negative force on Costco's stock during the period.

  • Tariff uncertainty adds cost risk Tariff uncertainty added cost risk for Costco, making its high valuation harder to justify. The stock's 46x price-to-earnings ratio became a concern as growth slowed.

    This highlights an external risk that weighed on the stock.

  • Expansion in China and green logistics Costco launched an exclusive JD.com partnership in China, anchored a $450 million Los Angeles mixed-use project, and opened a fully off-grid Florida distribution center cutting energy costs. These moves support long-term growth.

    This shows positive strategic actions that could drive future performance.

  • Potential Supreme Court tariff refunds A potential Supreme Court ruling could bring up to $175 billion in tariff refunds for import-heavy retailers like Costco, boosting cash flow and margins. However, the timing remains uncertain.

    This is a potential positive catalyst that could improve financials.

Costco expands in China and cities, cuts energy costs, tariff refunds loom

  • JD.com exclusive China e-commerce partnership Costco made JD.com its exclusive online sales partner in China, giving it a major digital channel in a huge market without building its own e-commerce operation. This expands reach to new customers and supports membership growth, a positive for the stock.

    New event that directly expands Costco's sales reach and long-term growth story.

  • Urban expansion tied to affordable housing Costco is anchoring a $450 million Los Angeles mixed-use project with 800 apartments, including affordable units, opening in 2028. This gives Costco scarce urban land and new customers while sharing development costs, supporting future sales growth.

    New strategic move that opens new store locations and customer bases.

  • Florida distribution center goes fully off-grid Costco's Port St. Lucie, Florida distribution center now runs entirely on on-site solar and batteries, cutting energy costs, avoiding utility rate hikes, and earning tax credits. Lower operating costs and better reliability support profits over time.

    New operational improvement that reduces costs and supports sustainability goals.

  • Supreme Court tariff ruling could bring refunds A Supreme Court ruling against Trump's broad tariffs could lead to up to $175 billion in refunds for import-heavy retailers like Costco. That would boost cash flow and margins, though payouts may take time and are not immediate.

    New legal development that could materially improve Costco's finances.

Costco's sales growth cools as fuel boost fades and price war looms

  • Fuel-driven sales boost fades Costco's comparable sales growth was inflated by high gas prices; as gas prices retreat, that boost disappears. Fuel-adjusted comps are running 4-5 percentage points lower, and the stock fell over 10% from its May high. This pressures COST because investors worry the underlying sales trend is weaker than reported.

    This is a key new reason for the stock's decline, showing a hidden weakness in sales growth.

  • June comparable sales growth decelerates Costco reported June comparable sales growth of 8.8%, down from 12.5% in May. Adjusted for gas and currency, growth cooled to 7% from 8% in May. The stock fell 4% on the news. Slowing growth makes Costco's high valuation (46 times earnings) harder to justify, pushing the price down.

    This is the latest hard data showing a clear slowdown in sales growth, directly impacting the stock.

  • Grocery price war with Walmart and Kroger Walmart and Kroger are cutting food prices to attract budget-conscious shoppers, potentially starting a broader grocery price battle. Costco may have to lower prices or accept thinner margins to stay competitive. While Costco's low-price model and membership income help, protecting profits will be tough if rivals keep discounting.

    This new competitive threat could pressure Costco's margins and sales, a key concern for investors.

  • Tariff deadline adds cost uncertainty A temporary 10% tariff on Chinese imports expires July 24, and retailers are rushing to import goods before it possibly rises to 12.5%. Costco sources heavily from China, so higher tariffs would raise its costs. This uncertainty weighs on the stock as investors assess potential profit impact.

    This is a new regulatory risk that could increase Costco's costs and reduce earnings.

Q2 2026

Costco's strong sales and membership growth face high valuation and slowing traffic

  • Strong Q3 earnings and sales growth Costco reported a 15% jump in net income to $2.19 billion and net sales up 11.6% to $69.15 billion. Comparable sales grew 9.8%, and membership fee income rose 10.7%. This shows the core business is thriving, which supports the stock price.

    This is the latest earnings report, a key driver of the stock's fundamental value.

  • Resilient sales despite Fed holding rates The Fed kept interest rates steady at 3.5%-3.75%, with inflation still high. Costco's May comparable sales jumped 12.5%, showing it can attract shoppers even when rates are high. This resilience makes the stock appealing in uncertain times.

    It highlights Costco's ability to perform well regardless of monetary policy, a key concern for investors.

  • Slowing warehouse traffic growth Worldwide warehouse traffic grew only 2.4% in the latest quarter, a slowdown that challenges the idea that frequent visits will keep driving sales. If traffic growth stays weak, investors may worry about future comparable sales and the stock's high valuation.

    This is a new negative development that could pressure the stock if the trend continues.

  • High valuation and analyst caution Costco stock trades near $1,000 with a P/E around 47, which is expensive. Analysts see 16% upside on average, but some warn of a pullback to the low $900s. The high price means the stock is vulnerable if growth slows.

    Valuation is a major factor in whether the stock can rise further or is due for a correction.
