Costco Wholesale Corporation (COST) Earnings Review

Executive Summary

Costco Wholesale Corporation has reported, and this is the earnings review: what the quarter delivered against the Street's expectations, and what it means for the underlying business. Reported EPS landed at $4.93 against the $4.92 consensus — a surprise of 0.14% — on revenue of $70.53B versus a $70.08B estimate.

An earnings print only matters if it connects to the durable trend. The trailing-twelve-month revenue change is 9.23% while the TTM EPS change is 13.47%, so the rest of this review tests whether the quarter reinforced that direction across cash flow, margins, and the forward setup rather than simply clearing a bar.

The Quarter Reported

Start with the scorecard. Costco Wholesale Corporation posted EPS of $4.93 against the $4.92 analysts modeled, an EPS surprise of 0.14%, while revenue of $70.53B compared with the $70.08B consensus for a revenue surprise of 0.64%.

The two surprises together say more than either alone, because a revenue-led result is more durable than one carried by a tax item or a share-count effect on EPS. This section treats the print as a data point about execution against expectations; whether it changed the thesis is decided by the trend lines and the forward outlook below.

Revenue And Earnings Direction

The TTM revenue change of 9.23% is most useful beside the net income change of 12.69%. When sales and earnings move apart, the review shifts from a growth story to a margin story. The EPS change of 13.47% then shows what the latest reporting cycle actually delivered per share after buybacks and mix.

Cash Flow Conversion

Cash conversion is the honesty check on the earnings line. The free-cash-flow change of 20.35% either confirms the EPS result or challenges it, and an earnings review is incomplete when it reports a beat or miss without asking whether cash generation moved the same way.

Margin Quality

Margin quality decides whether the revenue base is becoming more profitable. Operating margin is 3.82%, gross margin is 12.88%, and net margin is 3.01%. The margin chart belongs here because this is the section that explains why earnings can diverge from sales after a print.

Forward Outlook

The market trades on the next quarter, not the last one. Consensus models $6.49 in EPS and $94.40B in revenue for the coming quarter, with the next report due September 24, 2026. The forward setup is what turns a backward-looking print into a thesis: a result paired with a soft forward bar reads very differently from one paired with a rising one.

Comparing the just-reported quarter against that forward estimate is the cleanest way to see whether expectations are catching up to the business or running ahead of it. The TTM revenue change of 9.23% is the reference point for judging whether the next-quarter bar looks conservative or demanding.

Valuation Reset

Valuation resets with every print. The market is paying 47.91x trailing earnings and the free-cash-flow yield is 2.08%. A quarter matters most when the valuation has not already priced every improvement in advance, so the multiple is the lens that decides how much the surprise should move the view.

Bull/Bear Case

The bull case is that revenue, earnings, cash flow, and margins moved together this quarter while the valuation at 47.91x remains explainable against the forward setup. The bear case is a split between reported earnings and cash generation, or a forward bar that asks too much of the next print. The case work sits before the final read so the review does not end as a recap.

Final Research Read

The earnings review is useful only when the print, the trend lines, cash conversion, margin quality, the forward outlook, and the valuation reset tell a coherent story.
