Costco (COST) Q4 Earnings Preview: What You Should Know Beyond the Headline Estimates

Costco (COST) is projected to report Q4 EPS of $5.81, a 12.8% year-over-year increase, on $86.23 billion in revenue, up 8.2% YoY, with analysts having recently revised the consensus EPS estimate upwards by 0.4%. While total comparable sales are forecast to grow 5.5% and ex-FX/gas comparable sales are expected at 6.5% (a slight deceleration from 6.9% year-ago), regional performance shows mixed trends, with U.S. comparable sales accelerating to 5.6% and Other International to 8.4%.

Analysis

Costco is poised to report strong fourth-quarter results, with consensus estimates projecting a 12.8% year-over-year increase in EPS to $5.81 and an 8.2% rise in revenue to $86.23 billion. Bullish sentiment is supported by a recent 0.4% upward revision in the consensus EPS estimate over the last 30 days, a historically strong indicator of short-term price performance. A deeper look at key metrics reveals a nuanced picture: while total company comparable sales are expected to slightly accelerate to 5.5% from 5.4% a year ago, this is largely driven by headline strength in U.S. and International segments. Conversely, core comparable sales, which exclude gasoline and foreign exchange impacts, are forecast to decelerate to 6.5% from 6.9% in the prior year, with this moderation seen across all geographic regions. This divergence suggests that while top-line growth remains robust, aided by continued warehouse expansion, the underlying organic sales momentum is slowing. The stock's recent underperformance, declining 0.8% over the past month against the S&P 500's 4% gain, may reflect investor apprehension regarding this core deceleration ahead of the earnings release.

Key Decisions for Investors

• Investors should scrutinize the core comparable sales figure (ex-gas/FX), as a miss on this metric could overshadow beats on headline revenue and EPS, potentially triggering a negative reaction given the forecast deceleration to 6.5%.
• Pay close attention to the geographic breakdown of sales, particularly the 'Other International' segment, where analysts expect strong headline comp acceleration but a significant core comp slowdown, making it a key source of potential earnings surprise or disappointment.
• Given the stock's recent underperformance and the mixed signals between strong headline growth and moderating core trends, a neutral stance may be prudent; a significant beat on core comps would be a key bullish catalyst, whereas merely meeting expectations may not be sufficient to drive the stock higher.
