Costco’s Membership Model Still Looks Unstoppable

That wraps up our initial coverage of Costco’s Q3 results. Thank you for stopping by!

With Costco’s Q3 earnings report behind us, the narrative now hinges on what management says and what the calendar delivers next.

What Moves $COST From Here

• Tonight’s call: The conference call at 5:00 PM ET will frame tariff mitigation, renewal cadence, and whether the EPS miss reflects LIFO or deeper margin pressure.
• Monthly comps: Costco’s monthly comparable sales releases give real-time read-throughs before the next quarter’s results.
• Next earnings: Q4 FY2026 results expected September 2026 will close out the fiscal year and set FY27 expectations.
• Warehouse cadence: Progress toward 942 total locations and any Kirkland price actions.
• Capital return: Special-dividend chatter and the $1,076.97 analyst target anchor upside.

History suggests patience, because beats have averaged a -1.18% one-week drift, so post-call earnings commentary can impact what comes next for the stock.

Costco (NASDAQ:COST) shares are essentially unchanged after Q3 earnings results. Given a $70.53B revenue beat against a $4.93 vs. $4.97 EPS miss, a flat reaction seems to make sense.

Shares already slid -6.55% last week, trimming risk ahead of results.

Q1 FY26 also closed 0% on a beat before recovering +8.17% over 30 days. At 52x earnings, the market is reserving judgment until the call clarifies comps, renewal trends, and tariff exposure.

Costco just reported earnings with shares trading roughly flat following a mixed quarter that included a slight EPS miss but stronger-than-expected revenue growth.

Here are the key numbers:

Revenue: $70.53B vs. $69.64B expected
Adjusted EPS: $4.93 vs. $4.97 expected

Quick read:

• Costco narrowly missed EPS estimates but still delivered strong top-line growth, with revenue rising 12% year over year.
• The report reinforces Costco’s reputation as one of retail’s most resilient operators, though investors likely wanted a cleaner beat given the stock’s premium valuation near all-time highs.

Costco reports earnings tonight, May 28, with investors looking for another near-perfect quarter from one of retail’s most consistent winners. Wall Street expects roughly $69.7 billion in revenue, comparable sales growth near 6.7%, and EPS of $4.97. But with the stock recently pulling back from all-time highs, expectations remain high.

One of the biggest themes tonight will be how consumers are responding to higher fuel costs and inflation pressures. Analysts believe Costco may actually benefit from rising gas prices as members consolidate spending trips and increasingly use Costco fuel stations, potentially boosting both traffic and basket sizes.

Investors will also watch closely for commentary around membership renewals, international expansion, and the possibility of another special dividend. Costco last paid a special dividend in January 2024, and some investors believe another payout cycle may be approaching.

With the call set for 4:15 PM ET, here’s what to listen for beyond the headline beat.

Top 5 Analyst Questions

• How is Kirkland Signature absorbing tariff costs, and what share is being passed to members?
• Can the 89.7% renewal rate hold past the fee-hike anniversary?
• Pace toward 942 warehouses in FY26 after only 10 openings YTD?
• Is +22.6% digital comp growth sustainable?
• Any update on capital return after $419M in buybacks?

Buzzwords

Listen for “core-on-core margin,” “tariff mitigation,” “local sourcing,” “ticket vs. traffic,” and “executive penetration.”

Red Flags

• Renewal slipping below 89.7%
• Gross margin contraction beyond LIFO
• Big-ticket discretionary softening as Michigan sentiment sits at 49.8
• Insider selling continuing after four EVP dispositions in March-April

Less than an hour until the bell, and Costco (NASDAQ:COST) is consolidating in a tight band. The stock printed an intraday high of $1,012 at the open before drifting to $999.35 by 3:00 PM ET on declining volume, a classic pre-release positioning pattern.

Trigger Levels to Watch

• Upside catalyst: Comp sales above 7.4% plus renewal rate ticking back toward 90.2%.
• Downside trigger: Any renewal slip below 89.7%, or cautious tariff guidance.
• Volatility precedent: Recent day-of ranges have spanned $21 to $50.

With analysts targeting $1,076.97 and shares near the 50-day moving average of $1,007.92, tonight’s report sets the next directional leg.

With Costco (NASDAQ:COST) reporting tonight at 4:15 PM ET, expectations are stretched. No formal Q3 FY26 consensus was provided, but the year-ago numbers sit at $4.28 EPS on $63.21B in revenue, with comparable sales of +5.7% as the comp to beat.

Key KPIs: comp sales (last quarter +7.4%), worldwide renewal at 89.7%, digitally-enabled comp of +22.6%, and membership fees of $1.355B (+13.6%).

Shares trade at $998.51, off 6.55% over the past week but up 16.72% YTD. At a forward P/E near 45x, investors are expecting a strong beat tonight.

Polymarket assigns a 95% probability of a beat, climbing from 88% yesterday. Renewal-rate slippage or cautious tariff commentary could pressure shares, while firm membership trends and durable margins would reinforce the stock’s narrative as a compounder.

With Costco (NASDAQ:COST) reporting Q3 earnings tonight at 4:15 PM ET, here’s a quick refresher on both sides of the debate heading into the earnings report.

Bull Case

• Membership flywheel: Costco grew fee income +13.6% last quarter with a 89.7% worldwide renewal rate.
• Consistent beats: 7 of the last 8 quarters topped consensus.
• Digital surge: +22.6% e-comm comps and +63% app visits.
• Crowd confidence: Polymarket prices a 95% beat probability.

Bear Case

• Rich valuation: A 47x forward P/E leaves no margin for error.
• Consumer chill: Michigan sentiment fell to 49.8 in April, near recessionary territory.
• Post-beat fade: Average 1-week return after recent beats is -1.18%.
• Cost pressures: Tariffs, wage hikes, and LIFO charges threaten margins, while shares already slipped -6.55% over the past week.

Costco reports Q3 earnings tonight after a recent pullback from May highs. At roughly 47 times forward earnings and a market cap approaching $445 billion, investors continue pricing Costco as one of the market’s most reliable compounders.

That leaves little room for disappointment. Wall Street will watch closely for strong comparable sales growth, healthy membership renewal rates, and management commentary around tariffs and consumer spending trends.

Strong Q3 results would reinforce the view that Costco remains one of retail’s safest long-term winners. But if growth or guidance comes in softer than expected, the recent decline could continue as investors reassess how much they are willing to pay for consistency.
