Costco operates a membership-only warehouse club model, requiring customers to pay annual fees that generate an annuity-like income stream. In fiscal 2025, Costco collected over $4.2 billion in membership revenues—representing roughly 80% of its operating income—while maintaining product gross margins near 12.9%. This structure allows the company to price goods at lower markups than traditional retailers, driving high membership renewal rates above 91% in the United States and Canada and fueling same-store sales growth of 8.1% year over year.

Shares of Costco trade at a price-to-sales ratio of 1.5, compared with a five-year average of 1.2, and a price-to-earnings ratio of 51 versus its longer-term average of 44. The price-to-book multiple stands at 14.1 against a historical average of 12.4. Its dividend yield of 0.5% is near the lowest level seen in the past decade. With a market capitalization of $428 billion, Costco’s valuation metrics suggest investors are assigning a higher premium than at any point in the last five years.

Costco continues to drive long-term growth through an accelerated warehouse opening program and innovative site reuse. In fiscal 2025, the company added 26 new club locations—expanding its global footprint to 848 warehouses across 12 countries—and achieved an average payback period of under two years per new store. Additionally, management has repurposed more than 40 former big-box retail sites, reducing build-time by six months on average and cutting development costs by 15%.

Despite a modest yield, Costco has increased its annual dividend for 22 consecutive years, with a compound annual growth rate of 8.5% over the past decade. Free cash flow reached $8.7 billion in fiscal 2025, providing ample coverage for a dividend payout ratio below 25%. The company’s strong cash generation supports strategic reinvestment in infrastructure, technology and further warehouse growth without compromising its commitment to returning capital to shareholders.
