Costco Q4 Earnings Preview: Is Now the Right Time to Buy the Stock?

Costco Wholesale Corporation (COST) is set to report Q4 fiscal 2025 earnings on September 25th, with analysts anticipating $86.23 billion in revenue (up 8.2% YoY) and $5.82 EPS (up 13% YoY). The company has already reported strong preliminary Q4 net sales of $84.4 billion, an 8% increase, driven by 5.7% comparable sales growth and a 13.6% surge in e-commerce, alongside robust membership renewal rates exceeding 90%. However, despite these operational strengths and its resilient membership-driven model, COST trades at a significant premium (forward P/E of 47.13 vs. industry 30.13), and the Zacks model does not conclusively predict an earnings beat, suggesting a cautious approach for new investors while current holders may find it prudent to maintain positions.

Analysis

Costco approaches its Q4 earnings announcement with demonstrated top-line strength, having already reported preliminary net sales of $84.4 billion, an 8% year-over-year increase. This growth is supported by solid comparable sales, which rose 5.7% globally, and a significant 13.6% surge in e-commerce comps. The company's core business model remains robust, evidenced by membership renewal rates exceeding 90% and an anticipated 10.5% rise in high-margin membership fee income, providing a dependable revenue foundation. However, this operational strength is juxtaposed with significant valuation concerns. The stock trades at a forward P/E ratio of 47.13, a substantial premium to its industry average of 30.13 and key retail peers. Furthermore, despite optimistic analyst consensus for 13% EPS growth, the Zacks model does not conclusively predict an earnings beat, citing a negative Earnings ESP of -0.74%. This, combined with potential headwinds from inflationary pressures and an expected 6.8% increase in SG&A expenses, introduces a degree of caution and suggests that while fundamentals are strong, the stock is priced for perfection.

Key Decisions for Investors

• Given the combination of strong operational metrics and a high valuation, current holders may consider maintaining their positions but should be prepared for potential volatility post-earnings.
• New investors should exercise caution, as the premium P/E ratio of 47.13 and the inconclusive earnings beat model suggest a less favorable risk/reward profile; waiting for the earnings release for a better entry point may be prudent.
• All investors should closely scrutinize the upcoming report for margin performance, particularly the impact of SG&A expenses, and management's forward guidance to assess if future growth can justify the current valuation.
